Whereas the wkup_r5fss0_core0_dma_memory_region is used for allocating the Virtio buffers needed for IPC with the DM core which could be optional. The labels were incorrectly used in the k3-am62p-verdin.dtsi file. Correct the firmware memory region label. Currently, only mailbox node is enabled with FIFO assignment. However, there are no users of the enabled mailboxes. Add the missing carveouts for WKUP and MCU R5F remote processors, and enable those by associating to the above carveout and mailboxes. This config aligns with other AM62P boards and can be refactored out later.
