The A31 has a reset controller IP that maintains a few other IPs in
reset, among which we can find the UARTs, high speed timers or the I2C.
Now that we have support for them, add the reset controllers to the DTSI.

The APB2 clocks gates are only a 32 bits register wide, and not 2 as set
currently in the DTSI.

Now that the clock driver has support for the A31 clocks, we can add
them to the DTSI and start using them in the relevant hardware blocks.

The A31 has a different set of pins than the one found on the A10 and
A13. Now that we have support for the A31 pin set in the pinctrl driver,
we can enable it in the DTSI with its own compatible.
