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.

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.

All dts files for the sunxi platform have been switched to the generic
pinconf bindings. As a result, the sunxi specific pinctrl macros are
no longer used.
Remove the #include entry with the following command:
sed --follow-symlinks -i -e '/pinctrl\/sun4i-a10.h/D' \
arch/arm/boot/dts/sun?i*.*
arch/arm/boot/dts/sun9i-a80.dtsi was then edited to remove the extra
empty line.

Currently none of the target boards nor the driver supports
IR TX. However this pin is used in a few instances as a GPIO.
Split the pin ctrl descriptions so that only the IR RX is
configured to be used.

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.

The current GPL only licensing on the DTSI makes it very impractical for other

In order to make it easier for them to reuse our device trees, relicense our
device trees under a GPL/X11 dual-license.

At a node for the axp209, and where necessary the i2c controller to the dts
for various boards. Note the axp209 regulators are omitted as we don't have
any use for them yet, and on some boards were not sure how exactly they are
wired up.
Adding support for just the axp209 without the regulators is still useful, as
it will give us power-button and poweroff support.
