The Allwinner A523/T527 SoCs have four CCUs, this adds the binding for
the PRCM R_CCU.

Add the new compatible string, along with the required input clock
lists. There is now an extra input clock (PLL_AUDIO), so add this to the
list of allowed clocks and required it for the A523 PRCM CCU.
Also add the DT binding headers, listing all the clocks with their ID
numbers.
