For am62x and am62ax devices, this patch series adds device nodes
for the R5F subsystem and C7xv DSP subsystem found in their
respective voltage domain, based on the device TRMs [0][1].

This patch series also includes patches for enabling IPC for am62x SK,
am62ax SK, and am62px SK by reserving memory and binding the mailbox
assignments for each remote core.

Also reserve timers used by C7x DSP for am62ax SK board and timers used
by MCU FW for AM642 SK and EVM boards as per firmware requirements.

Changes since v4:
- Drop SRAM node for am62px/am62ax MCU R5fSS0 core0
- Reserve timers for am64 MCU FW, patch 10/10
- Add "status = okay" for mailbox nodes at the board level, disabling of
  mailbox nodes in voltage domain .dtsi files will come in a separate
  series
