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.

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.

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.

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.

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 Point of View protab2-ips9 is a tablet with a 9" ips 1024x768 lcd screen,
microsd slot, headphones, mini hdmi, mini usb b and power barrel connectors.
It uses a rtl8188cus usb wifi chip and a RDA 5875Y bluetooth chip attached
to uart2. It has a bma250 accelerometer attached to i2c1 addr 0x18, this
only works when ldo3 is set to 2.8 volt, otherwise i2c1 gets stuck, so
for now we mark i2c1 as failed.
It has a pixcir,pixcir_tangoc compatible touchscreen attached to i2c2 addr
0x5c. This is not enabled in this dts, because this variant of the
pixcir_tangoc has separate wakeup and enable pins both of which need
to be driven low before the touchscreen will work. Before we can enable
this the pixcir driver and devicetree-bindings need to be extended to
support these pins.
