The I2C's, MMC0 and MMC1 controllers have only one muxing option in the
SoC. In such a case, we can just move the muxing into the DTSI, and remove
it from the DTS.

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.

Boards usually have an external pull-up on the card-detect signal, so
there's no need to add another one.
This also removes a DTC warning.

The gpio pinctrl nodes are redundant and as such useless most of the times.
Since they will also generate warnings in DTC, we can simply remove most of

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.

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.
