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.

So far we've enabled pull-up and pull-down resistors on GPIOs using a
pinctrl node. Now that the GPIO binding allows for a flag to declare this,
let's switch to it.
This brings us closer to removing all the GPIO pinctrl nodes, which will in
turn allow us to switch the pinctrl strict mode on.

While the USB PHY Device Tree mandates that the name of the ID detect pin
should be usb0_id_det-gpios, a significant number of device tree use
usb0_id_det-gpio instead.
This was functional because the GPIO framework falls back to the gpio
suffix that is legacy, but we should fix this.

Some GPIO pinctrl nodes cannot be easily removed, because they would also
change the pin configuration, for example to add a pull resistor or change
the current delivered by the pin.
Those nodes still have underscores and unit-addresses in their node names
in our DTs, so adjust their name to remove the warnings. Use that occasion
to also fix some poorly chosen node-names.

All our pinctrl nodes were using a node name convention with a unit-address
to differentiate the different muxing options. However, since those nodes
didn't have a reg property, they were generating warnings in DTC.
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.

One of the usage of the LRADC is to implement buttons. The bindings define
that we should have one subnode per button, with their associated voltage
as a property.
However, there was no reg property but we still used the voltage associated
to the button as the unit-address, which eventually generated warnings in
DTC.
Rename the node names to avoid those warnings.

Using the cd-inverted property is not useful when GPIOs are used as card
detects since the polarity can be specified with the usual
GPIO_ACTIVE_(HIGH|LOW) GPIO flags. It has also caused confusion for
U-Boot developers, so migrate all sunxi boards away from cd-inverted.

Pull ARM SoC DT updates from Olof Johansson:
"DT changes continue to be the bulk of our merge window contents.
We continue to have a large set of changes across the board as new
platforms and drivers are added.
Some of the new platforms are:
- Alphascale ASM9260
- Marvell Armada 388
- CSR Atlas7
- TI Davinci DM816x
- Hisilicon HiP01
- ST STiH418
There have also been some sweeping changes, including relicensing of
DTS contents from GPL to GPLv2+/X11 so that the same files can be
reused in other non-GPL projects more easily. There's also been
changes to the DT Makefile to make it a little less conflict-ridden
and churny down the road"
