APB0 is bearly mentioned in H3 User Manual and it is only setup in the
Allwinners kernel dump for CIR. I have verified experimentally that the
gate for R_PIO exists and works, though. There are probably other gates
there but I don't know their order right now and I don't have access to
their peripherals on my board to test them.
