arm64: dts: fsl: Remove num-lanes property from PCIe nodes

Remove the num-lanes property to avoid the driver setting the
link width.

On FSL Layerscape SoCs, the number of lanes assigned to PCIe
controller is not fixed, it is determined by the selected SerDes
protocol in the RCW (Reset Configuration Word).

The PCIe link training is completed automatically through the selected
SerDes protocol - the link width set-up is updated by hardware after
power on reset, so the num-lanes property is not needed for Layerscape
PCIe.

The current num-lanes property was added erroneously, which actually
indicates the maximum lanes the PCIe controller can support up to,
instead of the lanes assigned to the PCIe controller. The link width set
by SerDes protocol will be overridden by the num-lanes property, hence
the subsequent re-training will fail when the assigned lanes do not
match the value in the num-lanes property.

Remove the property to fix the issue

arm64: dts: fsl: Add all CPUs in cooling maps

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.

Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.

Update cooling maps to include all devices affected by individual trip
points.

Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC device tree updates from Arnd Bergmann:
"There are close to 800 indivudal changesets in this branch again,
which feels like a lot. There are particularly many changes for the
NVIDIA Tegra platform this time, in fact more than it has seen in the
two years since the v4.9 merge window. Aside from this, it's been
fairly normal, with lots of changes going into Renesas R-CAR, NXP
i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP.

Most of the changes are for adding new features into existing boards,
for brevity I'm only mentioning completely new machines and SoCs here.
For the first time I think we have (slightly) more new 64-bit hardware
than 32-bit:

Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a
minor variation of the motherboards of the GTA04 phone, see
https://shop.goldelico.com/wiki.php?page=GTA04A5

Clearfog is a nice little board for quad-core Marvell Armada 8040
network processor, see
https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/

Two additional server boards come with the Aspeed baseboard management
controllers: Stardragon4800 is an arm64 reference platform made by HXT
(based on Qualcomm's server chips), and TiogaPass is an Open Compute
mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the
BMC.

NXP i.MX usually sees a lot of new boards each release. This time
there we only add one minor variant: ConnectCore 6UL SBC Pro uses the
same SoM design as the ConnectCore 6UL SBC Express added later.
However, there is a new chip, the i.MX6ULZ, which is an even smaller
variant of the i.MX6ULL, with features removed. There is also support
for the reference board design, the i.MX6ULZ 14x14 EVK.

A new Raspberry Pi variant gets added, this one is the CM3 compute
module based on bcm2837, it was launched in early 2017 but only now
added to the kernel, both as 32-bit and as 64-bit files, as we tend to
do for Raspberry Pi.

On the Allwinner side, everything is again about cheap development
boards, usually of the "Fruit Pi" variety. The new ones this time are:
- Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
- Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
- Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
- Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
The last one of these is now a 64-bit version of the earlier Banana Pi
M2+ H3, with the same board layout.

Similarly, for Rockchips, get get another variant of the 32-bit Asus
Tinker board, the model 'S' based on rk3288, and three now boards
based on the popular RK3399 chip:
- ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
- Rock960: https://www.96boards.org/product/rock960/
- RockPro64: https://www.pine64.org/?page_id=61454
These are all quite powerful boards with lots of RAM and I/O, and the
RK3399 is the same chip used in several Chromebooks. Finally, we get
support for the PX30 (aka rk3326) chip, which is based on the low-end
64-bit Cortex-A35 CPU core. So far, only the evaluation board is
supported.

One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is
based on the MT7622 WiFi router platform, and the first product I've
seen with a 64-bit Mediatek chip in that market:
http://www.banana-pi.org/r64.html

For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
development board, which are similar to the Hi3660 and Hikey 360
respectively, but add support for an NPU.

Amlogic gets initial support for the Meson-G12A chip (S905D2), another
quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit
side, we gain support for an actual end-user product, the Endless
Computers Endless Mini based on Meson8b (S805), see
https://endlessos.com/computers/

Qualcomm adds support for their MSM8998 SoC and evaluation platform.
This chip is commonly known as the Snapdragon 835, and is used in
high-end phones as well as low-end laptops.

For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
but no boards for this one. However, we do add boards for the
previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the
M3NULCB Starter Kit Pro.

While we have lots of DT changes for NVIDIA to update the existing
files, the only board that gets added is the Toradex Colibri T20 on
Colibri Evaluation Board for the old Tegra2.

Synaptics add support for their AS370 SoC, which is part of the
(formerly Marvell) Berlin line of set-top-box chips used e.g. in the
various Google Chromecast. Only the .dtsi gets added at this point, no
actual machines"
