The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.
There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.

The S3C RTC requires 32768 Hz clock as input which is provided by PMIC.
However there is no clock provided for the PMIC and the driver registers
the clock as regulator. This is an old driver which will not be updated
so add a workaround - a fixed-clock to fill missing clock phandle
reference in S3C RTC.
This allows to enable the S3C RTC and fixes dtbs_check warnings:
arch/arm/boot/dts/exynos4210-smdkv310.dt.yaml: rtc@10070000: clocks: [[5, 346]] is too short

Usage of DTS macros instead of hard-coded numbers makes code easier to

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
functional changes.

MFC device can be used without any external hardware dependencies (when
IOMMU is enabled), so it can be enabled by default (like it has been
already done for Exynos 542x platforms). This unifies handling of this
device for Exynos3250, Exynos4 and Exynos542x platforms. Board can still
include exynos-mfc-reserved-memory.dtsi to enable using this device
without IOMMU being enabled.

Though the keyboard and other driver will continue to support the legacy
"gpio-key,wakeup", "linux-keypad,wakeup" boolean property to enable the
wakeup source, "wakeup-source" is the new standard binding.
This patch replaces all the legacy wakeup properties with the unified
"wakeup-source" property in order to avoid any further copy-paste
duplication.

Currently all boards must explicitly disable all unused device tree
nodes of unused components (e.g. i2c, sdhci, etc...). This makes it
necessary to all boards to be aware of all components on the SoC, which
in turns makes board dts files longer and more difficult to maintain
(e.g. adding new components to SoC-level tree requires adding nodes with
status="disabled" to every board).
This patch changes "status" of all optional components in SoC-level dts
file to "disabled", adds status="okay" to respective nodes of used
components in dts of all boards and removes all nodes with only
status="disabled" from boards dts.
