And moves stuff between the A23 DTSI and sun8i DTSI.

All these things should be in separate patches.

Apart from that, as I told on IRC, I'd really like to have the H3
support merged and support for the A33 and H3 settle down a bit before
we create such a DTSI.

There's a lot of IPs that are enabled here that I'm pretty sure have
never been tested and/or even apply to the H3 and/or A33 (PRCM, arch
timers, A10 timers, etc.)

So let's merge everything in separate DTSI, and then, once we have a
clear view of what needs what, we will create a common DTSI.
