Subject: [PATCH v3 0/9] Add R5F and C7xv device nodes

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 v2:
- Fix memory carvout sizes, remove leading zeros
- Reorder memory carveouts according to memory location
- Fix whitespace issues
- Fix commit headers, capitalize IPC and R5F
