clk: sunxi-ng: add support for the A523/T527 PRCM CCU

Browse source

The A523/T527 SoCs have clock/reset controls in the PRCM part, like many
previous SoCs. For a change, the whole PRCM is documented in the A523
manual, including the system bus tree, so we can describe all those
clocks correctly based on that. There layout seems to be derived from
the H6 and H616 PRCM CCUs, though there are more clocks, and many clocks
have subtly changed.

Describe all the mod and gate clocks, including the three bus clocks
(R_AHB, R_APB0, and R_APB1).
