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,
am62ax, and am62px by reserving memory and binding the mailbox
assignments for each remote core.

Also reserve main_rti4 and main_timer2 for the C7x DSP as per
firmware requirements.

Changes since v3:
- Add SRAM child node for am62p MCU R5 core 0

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
