[PATCH 3/4] arm64: dts: imx943-evk: Add CM7 and CM33S nodes

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

Add remoteproc nodes for the two Cortex-M7 cores (CM7-0, CM7-1) and
the Cortex-M33S core, along with their respective reserved memory
regions for firmware, virtio device vrings, resource tables and
shared DMA pools. Enable the MU11, MU13 and MU15 mailbox units used
for inter-processor communication with each remote processor.
