ARM: dts: Move .dts files to vendor sub-directories

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.

ARM: dts: sunxi: Add mdio bus sub-node to GMAC

The DWMAC binding never supported having the Ethernet PHY node as a
direct child to the controller, nor did it support the "phy" property
as a way to specify which Ethernet PHY to use. What seemed to work
was simply the implementation ignoring the "phy" property and instead
probing all addresses on the MDIO bus and using the first available
one.

The recent switch from "phy" to "phy-handle" breaks the assumptions
of the implementation, and does not match what the binding requires.
The binding requires that if an MDIO bus is described, it shall be
a sub-node with the "snps,dwmac-mdio" compatible string.

Add a device node for the MDIO bus, and move the Ethernet PHY node
under it. Also fix up the #address-cells and #size-cells properties
where needed.

So far we've enabled pull-up and pull-down resistors on GPIOs using a

This brings us closer to removing all the GPIO pinctrl nodes, which will in

All our pinctrl nodes were using a node name convention with a unit-address

In order to accomodate for this, convert the old nodes to the syntax we've
been using for the new SoCs, including removing the letter suffix of the
node labels to the bank of those pins to make things more readable.
