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-am62-pocketbeagle2.dts file. Correct the firmware memory region label Currently, only mailbox node is enabled with FIFO assignment for a single M4F remote core. Add the missing carveouts for WKUP R5F remote processor, and enable that by associating to the above carveout and mailbox. This config aligns with other AM62 boards and can be refactored out later.
