arm64: dts: allwinner: a523: Add MCU PRCM CCU node
Add a device node for the third supported clock controller found in the
A523 / T527 SoCs. This controller has clocks and resets for the RISC-V
MCU, and others peripherals possibly meant to operate in low power mode
driven by the MCU, such as audio interfaces, an audio DSP, and the NPU.
