ARM: dts: sunxi: Switch MMC nodes away from cd-inverted property
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.

012d5f389c ARM: dts: sun4i: Remove underscores from nodes names
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.

bca0d7d9ff ARM: dts: sun4i: Provide default muxing for relevant controllers
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.

e53bd7618d ARM: dts: sun4i: Change pinctrl nodes to avoid warning
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.

86f8b2d359 ARM: dts: sun4i: Change LRADC node names to avoid warnings
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.

75539f68a4 ARM: dts: sun4i: Remove all useless pinctrl nodes
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.

cf439662af ARM: sunxi: Drop mmc0_cd_pin_reference_design pinmux setting
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.

85d2913614 ARM: dts: sunxi: Remove no longer used pinctrl/sun4i-a10.h header
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.

119c366aea ARM: sunxi: Remove useless allwinner,pull property
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.
