The AM62x SoCs of the TI K3 family have a Cortex M4F core in the MCU
domain. This core can be used by non safety applications as a remote
processor. When used as a remote processor with virtio/rpmessage IPC,
two carveout reserved memory nodes are needed.

Disable by default as this node is not complete until mailbox data
is provided in the board level DT.
