Subject: [PATCH v2 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 v1:
- add patches 5-9 to enable ipc and complete device nodes
- disable each device node in the voltage domain files and
  enable at the board level file
- fix firmware names
