arm64: dts: ti: k3-am62-phycore-som: Enable Co-processors

For every remote processor, set up dedicated memory regions and
associate the required mailbox channels. Allocate two memory areas
per remote core: one 1MB region for vring shared buffers, and
another for external memory used by the remote processor for its
resource table and trace buffer.
