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.

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.

The I2C's, MMC0 and EMAC 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.

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.

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,drive property set to 10mA was really considered as our
default. Remove all those properties entirely to make that obvious.

The FSF address triggers a warning on checkpatch, saying that the FSF
license is already present in the Linux source code, and that it has
already changed in the past.
Remove it from our DT, as suggested.

Add UART aliases and stdout-path property for all the Allwinner boards so that
we won't have to rely on the bootargs' console= value, while working with
legacy bootloaders.
While we're at it, also remove the mentions of earlyprintk in the bootargs,
that will remove our default bootargs entirely, and allow the kernel to boot on
a system even if DEBUG_LL is configured for another system.
