61977ccf65 dt-bindings: reset: sun55i-a523-r-ccu: Add missing PPU0 reset
There is a PPU0 reset control bit in the same register as the PPU1
reset control. This missing reset control is for the PCK-600 unit
in the SoC. Manual tests show that the reset control indeed exists,
and if not configured, the system will hang when the PCK-600 registers
are accessed.

Add a reset entry for it at the end of the existing ones.

52dbf84857 dt-bindings: clk: sunxi-ng: document two Allwinner A523 CCUs
The Allwinner A523/T527 SoCs have four CCUs, this adds the binding for
the main and the PRCM R-CCU.

The source clock list differs in some annoying details, and folding this
into the existing Allwinner CCU clock binding document gets quite
unwieldy, so create a new document for these CCUs.
Add the new compatible string, along with the required input clock
lists. This conditionally describes the input clock lists, to make
adding support for the other two CCUs easier.

Also add the DT binding headers, listing all the clocks with their ID
numbers.
