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.

Nodes in device tree should be sorted by unit-address, followed by nodes
without a unit-address, sorted alphabetically. Some exceptions are the
top-level aliases, chosen, firmware, memory and reserved-memory nodes,
which are expected to come first.
These rules apply recursively with some exceptions, such as pinmux nodes
or regulator nodes, which often follow more complicated ordering (often
by "importance").
While at it, change the name of some of the nodes to follow standard
naming conventions, which helps with the sorting order and reduces the
amount of warnings from the DT validation tools.

The node names should be generic and DT schema expects certain pattern
(e.g. with key/button/switch).

GPIO hog nodes must have a "hog-" prefix or "-hog" suffix according to
the DT schema. Rename all such nodes to allow validation to pass.

Tuple boundaries should be marked by < and > to make it clear which
cells are part of the same tuple. This also helps the json-schema based
validation tooling to properly parse this data.
While at it, also remove the "immovable" bit from PCI addresses. All of
these addresses are in fact "movable".

The new json-schema based validation tools require SD/MMC controller
nodes to be named mmc. Rename all references to them.

"simple-panel" is a Linux driver and has never been an accepted upstream

Support the V1.1 hardware revisions with the following change:
Changed power rail for MMC1 interface to a 3.3V/1.8V switchable rail in
order to be able to run UHS SD cards in ultra high speed 1.8V mode.
