The I2C and MMC 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.

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
them.

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.

"bcrmf" is a typo and "wifi" is the preferred form to describe
such node, so change it accordingly.

As part of our effort to move pinctrl/GPIO interlocking into the
driver where it belongs, this patch drops the definition and usage
of the mmc0_cd_pin_reference_design pinmux setting for the default
mmc0 card detect GPIO pin.

The allwinner,pull property set to NO_PULL was really considered our
default (and wasn't even changing the default value in the code).
Remove these properties to make it obvious that we do not set anything in
such a case.

The Wits Pro A20 DKT is an A20 Development KiT with 1G RAM, 4G NAND,
sdio wifi, 1Gbit ethernet, 1024x768 lcd screen with ft5x_ts touchscreen
and a ton of IO connectors.
Note there seem to be multiple sdcard slots on the board (4 in total), but
other then mmc0 none of these are hooked up by default, there is a ton of
dip-switches which likely allow hooking some of these up, but the
documentation of the board only describes the use of a fraction of them,
so for now we only support mmc0.
