The I2C and MMC 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.

Boards usually have an external pull-up on the card-detect signal, so
there's no need to add another one.
This also removes a DTC warning.

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.

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.

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 A31/A31s devices I own have some kind of HDMI connector wired
to the dedicated HDMI pins on the SoC:
- A31 Hummingbird (standard HDMI connector, display already enabled)
- Sinlinx SinA31s (standard HDMI connector)
- MSI Primo81 tablet (micro HDMI connector)
Enable the display pipeline (if needed) and HDMI output for them.

While the SinA31s does have a proper 5-pin mini USB OTG port, the ID
pin does not seem to work. The pin used in the schematics is always low,
regardless of the attached OTG cable or SoC internal pin bias settings.
The v1.5 board is missing bias resistors shown in the schematics for
earlier revisions, and the connections of the remaining one does not
match the schematics either.
In addition, VBUS for this port is disconnected from the board's 5V
power rail. The board features a pad to solder jumper pins to connect
VBUS to 5V manually.
Given the above and the fact that the board has 5 more USB host ports,
it makes more sense to have the OTG port work in peripheral mode.

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 Sinlinx A31s SDK is a A31s based module/baseboard development kit.
The core module has the SoC, PMIC, DRAM, eMMC and supporting components.
There are also pads for UART0, JTAG and I2S.
The baseboard has 100 Mbps Ethernet, 5x USB 2.0 host ports via a USB 2.0
hub chip, MMC, HDMI, SPDIF, CIR, audio jacks, 2 tablet-like volume
buttons, RS232 style UART and USB OTG (though VBUS is not connected).
Various headers are available for other addon modules, such as SDIO
WiFi, LCD display, camera sensor, UARTs, I2C, SPI and GPIOs.
