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 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]
