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.

All the A20 devices I own have standard HDMI connectors wired
to the dedicated HDMI pins on the SoC:
- Bananapi M1+
- Cubieboard 2
- Cubietruck
- Lamobo R1 (or Bananapi R1)
Development boards from Olimex also have standard HDMI connectors.
Schematics for them are publicly available. Enable HDMI on them as
well.
- Olimex A20-OLinuXino-LIME
- Olimex A20-OLinuXino-LIME2
- Olimex A20-OLinuXino-MICRO
Enable the display pipeline and HDMI output for them.

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:

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

This patch adds the regulator nodes for the axp209 by including
the axp209 dtsi. As the inputs of these regulators are from the
axp209's PS output, which is basically just a mux over the 2
inputs, it is considered to be unregulated. Thus we do not provide
input supply properties for them.
The regulator names and constraints are based on the board
schematics and the SoC datasheet.
DCDC2 is used as the cpu power supply. This patch also references
it from the cpu node.
Also get rid of axp209 properties already set in axp209.dtsi.

Adding support for just the axp209 without the regulators is still useful, as
