Now that we support the HDMI controller on the A31 SoC, we can add it
to the device tree.

This adds a device node for the HDMI controller, and the of_graph nodes
connecting it to the 2 TCONs.

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 skeleton.dtsi will create a memory node that will generate a warning

The Allwinner R40 SoC is marketed as the successor to the A20 SoC.
The R40 is a smaller chip than the A20, but features the same set
of programmable pins, with a couple extra pins and some new pin
functions. The chip features 4 Cortex-A7 cores and a Mali-400 MP2
GPU. It retains most if not all features from the A20, while adding
some new features, such as MIPI DSI output, or updating various
hardware blocks, such as DE 2.0.

The TCONs on A31/A31s can select either backend as its input. As there
is no configurable mux in the backend or DRC to redirect their output,
or for the DRC to select an input, the connections are presumably from
the each DRC to each TCON, with the TCON having two input ports, like
the following diagram:

	Backend 0  -------  DRC 0  ------- [0]  TCON 0
				   --   -- [1]
                                     \ /
				      X
				     / \
				   --   -- [0]
	Backend 1  -------  DRC 1  ------- [1]  TCON 1
