arm64: dts: hi6220: Move board data from the dwmmc nodes to hikey dts

Move the board specific descriptions for the dwmmc nodes in the hi6220 SoC
dtsi, into the hikey dts as it's there these belongs.

While changing this, let's take the opportunity to drop the use of the
"ti,non-removable" binding for one of the dwmmc device nodes, as it's not a
valid binding and not used. Drop also the unnecessary use of "num-slots =
<0x1>" for all of the dwmmc nodes, as there is no need to set this since
when default number of slots is one.

arm64: dts: hi6220: Reset the mmc hosts

The MMC hosts could be left in an unconsistent or uninitialized state from

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

Pull ARM DT updates from Arnd Bergmann:
"Lots of changes as usual, so I'm trying to be brief here. Most of the
new hardware support has the respective driver changes merged through
other trees or has had it available for a while, so this is where
things come together.

We get a DT descriptions for a couple of new SoCs, all of them
variants of other chips we already support, and usually coming with a
new evaluation board:

- Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
- Qualcomm MDM9615 LTE baseband
- NXP imx6ull, the latest and smallest i.MX6 application processor variant
- Renesas RZ/G (r8a7743 and r8a7745) application processors
- Rockchip PX3, a variant of the rk3188 chip used in Android tablets
- Rockchip rk1108 single-core application processor
- ST stm32f746 Cortex-M7 based microcontroller
- TI DRA71x automotive processors

These are commercially available consumer platforms we now support:

- Motorola Droid 4 (xt894) mobile phone
- Rikomagic MK808 Android TV stick based on Rockchips rx3066
- Cloud Engines PogoPlug v3 based on OX820
- Various Broadcom based wireless devices:
- Netgear R8500 router
- Tenda AC9 router
- TP-LINK Archer C9 V1
- Luxul XAP-1510 Access point
- Turris Omnia open hardware router based on Armada 385

And a couple of new boards targeted at developers, makers or
industrial integration:

- Macnica Sodia development platform for Altera socfpga (Cyclone V)
- MicroZed board based on Xilinx Zynq FPGA platforms
- TOPEET itop/elite based on exynos4412
- WP8548 MangOH Open Hardware platform for IOT, based on Qualcomm MDM9615
- NextThing CHIP Pro gadget
- NanoPi M1 development board
- AM571x-IDK industrial board based on TI AM5718
- i.MX6SX UDOO Neo
- Boundary Devices Nitrogen6_SOM2 (i.MX6)
- Engicam i.CoreM6
- Grinn i.MX6UL liteSOM/liteBoard
- Toradex Colibri iMX6 module

Other changes:

- added peripherals on renesas, davinci, stm32f429, uniphier, sti,
mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
mvebu, allwinner, broadcom, exynos, zynq

- Continued fixes for W=1 dtc warnings

- The old STiH415/416 SoC support gets removed, these never made it
into products and have served their purpose in the kernel as a
template for teh newer chips from ST

- The exynos4415 dtsi file is removed as nothing uses it.

- Intel PXA25x can now be booted using devicetree"
