[PATCH v4 4/4] arm64: dts: ti: k3-am62a7-sk: Enable ipc with remote proc nodes

[Hari Nagalla]

From: Devarsh Thakkar <devarsht at ti.com>

Reserve memory for remote rpoc IPC and bind the mailbox assignments
for each remote proc. 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, resource table and as tracebuffer.
