[PATCH v3 5/7] arm64: dts: allwinner: a523: Add message box and remoteproc nodes

[Tim Michals <tcmichals@gmail.com>]

Add the message box node, with its four register banks, bank clocks
and resets, bank interrupts, and the XuanTie E906 remoteproc node,
with the MCU CCU clocks and resets, the RISC-V and SRAM power domains
and message box channel 9.

The remoteproc node is disabled; a board enables it together with its
firmware name and reserved memory regions.

Changes in v3:
- Message box: all four banks with their clocks and resets; the DSP and
  CPUS bank addresses were swapped in v2; remote bank interrupts
  corrected to SPI 181/174/205
- Message box: interrupt-names
- Remoteproc: debug reset, RISC-V and SRAM power domains, one message
  box channel; the message box clock and reset moved to the message box
  node; reg-names sram-a3-0 and sram-a3-1
