arm64: dts: meson: Fix erroneous SPI bus warnings

dtc has new checks for SPI buses. The meson dts files have a node named
spi' which causes false positive warnings. As the node is a pinctrl child
node, change the node name to be 'spi-pins' to fix the warnings.

ARM64: dts: meson-gx: fix ATF reserved memory region

Vendor firmware/uboot has different reserved regions depending on
firmware version, but current codebase reserves the same regions on
GXL and GXBB, so move the additional reserved memory region to common
.dtsi.

Found when putting a recent vendor u-boot on meson-gxbb-p200.

>From the hardware perspective, the actual pclk of the AO uarts

This was not problem so far, because the uart_gate had
the CLK_IGNORE_UNUSED flag, which kept the gate open.

We plan to remove the CLK_IGNORE_UNUSED flag in another patch,
but before doing that, we need to fix the clock in the DTS file.

ARM64: dts: meson-gx: fix gxl clock controller compatible

There are a few differences between the gxbb and gxl clock controllers
which makes them incompatible. The hdmi, gp0 and fixed pll are
different. The rate of these plls reported by gxbb driver on a gxl
device would be wrong.

Remove the gxbb compatible from the gxl clock controller node so only
the correct driver is matched.

ARM64: dts: meson-gxl: add USB host support

This adds USB host support to the Meson GXL SoC. A dwc3 controller is
used for host-mode, while a dwc2 controller (not added in this patch
because I could not get it working) is used for device-mode only.

The dwc3 controller's internal roothub has two USB2 ports enabled but no
USB3 port. Each of the ports is supplied by a separate PHY. The USB pins
are connected to the SoC's USBHOST_A and USBOTG_B pins.
Due to the way the roothub works internally the USB PHYs are left
enabled. When the dwc3 controller is disabled the PHY is never powered on
so it does not draw any extra power. However, when the dwc3 host
controller is enabled then all PHYs also have to be enabled, otherwise
USB devices will not be detected (regardless of whether they are plugged
into an enabled port or not). This means that only the dwc3 controller
has to be enabled on boards with USB support (instead of requiring all
boards to enable the PHYs additionally with the chance of forgetting to
enable one and breaking all other ports with that as well).

This also adds the USB3 PHY which currently only does some basic
initialization. That however is required because without it high-speed
devices (like USB thumb drives) do not work on some devices (probably
because the bootloader does not configure the USB3 PHY registers).

ARM64: dts: meson-gxl: Add alternate ARM Trusted Firmware reserved memory zone

This year, Amlogic updated the ARM Trusted Firmware reserved memory mapping
for Meson GXL SoCs and products sold since May 2017 uses this alternate
reserved memory mapping.
But products had been sold using the previous mapping.

This issue has been explained in [1] and a dynamic solution is yet to be
found to avoid loosing another 3Mbytes of reservable memory.

In the meantime, this patch adds this alternate memory zone only for
the GXL and GXM SoCs since GXBB based new products stopped earlier.
