Enable WiFi on this board by enabling mmc1 and adding the power

For the WiFi module to correctly detect the frequency of its main
oscillator, the external low power clock must be set to 32768 Hz.

Their does not seem to be proper out-of-band interrupt support
for the BCM4330 chip within the AP6330 module. This part is left

The AXP81x family of PMIC is used with the Allwinner A83T and H8 SoCs.
This includes the AXP813 and AXP818. There is no discernible difference
except the labeling. The AXP813 is paired with the A83T, while the
AXP818 is paired with the H8.

This patch adds a dtsi file for all the common bindings for these two
PMICs. Currently this is just listing all the regulator nodes. The
regulators are initialized based on their device node names.

In the future this would be expanded to include power supplies and
GPIO controllers.

Some GPIO pinctrl nodes cannot be easily removed, because they would also

Those nodes still have underscores and unit-addresses in their node names

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

However, there was no reg property but we still used the voltage associated

DTC.
