From: Hari Nagalla <hnagalla@xxxxxx>
For each remote proc, reserve memory for IPC and bind the mailbox
assignments. Two memory regions are reserved for each remote processor.
The first region of 1MB of memory is used for Vring shared buffers
and the second region is used as external memory to the remote processor
for the resource table and for tracebuffer allocations.

Changes since v4:
- 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
