2008ee090c Topic branch for Samsung DeviceTree cleanup for 4.9.
Replace in DT sources hard-coded values for pinctrl configuration like pull
 up/down, drive strength and function. This makes the DTS easier to read,
 especially that some drive strengths values are quite non-obvious.

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").

These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:

"Node /memory has a reg or ranges property, but no unit name"

The disassembled DTB are almost the same besides an empty chosen
node being removed and nodes reordered, so it should not have

4f0d20ec19 ARM: dts: Make CPU configuration more readable on exynos542x/5800
Exynos5420 and Exynos5800 boards boot from big core (A15) but
Exynos5422 boards choose otherwise: LITTLE core (A7) (on Exynos5422 this
is property of the board - configurable by pulling up/down gpg2-1).
To make user-visible CPU ordering more consistent the 'cpus' node was
overridden by exynos5422-cpus.dtsi.

However this is a little bit ugly and error-prone. Overriding the CPU
child nodes requires to basically reverse what was done initially in
exynos5420.dtsi.

Instead, split CPU configuration entirely to separate files which should
be included by board DTS.

af6ad88acb ARM: dts: Mux XMMCnDATA[0] pad correctly for Exynos5420 boards
The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3
MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a
GPIO or external interrupt to allow the MMC controller to communicate
with the attached cards or SDIO devices.

Which data lines needs to be muxed as SD_n_DATA depends on the bus
width used for data transfer:

* bus-width = <1> needs SD_n_DATA[0]
* bus-width = <4> needs SD_n_DATA[0-3]
* bus-width = <8> needs SD_n_DATA[0-7]

The Exynos5250-pinctrl.dtsi file that defines the groups of pins has
SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them
needs to be included in the device node's pinctrl property.

But Exynos5420-pinctrl has a different definition and only includes
SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1
and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads.

It seems all Exynos5420 boards had just cargo cult the pinctrl lines
assuming that sdn_bus4 also included SD_n_DATA[0] and it only works
because the bootloader muxes the pads correctly. But that is not the
case for the devices not used by the bootloader such as WiFi modules.

Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.

Without this patch:

- "mmc: dw_mmc: Support voltage changes" patch causes a boot hang

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced with "cap-sd/mmc-highspeed".
