Line 51 exceeds 80 columns; consider breaking memory-region into
multiple lines for readability.

Consider adding a comment explaining the 16 MB reservation size and
purpose (firmware load address, etc.).

Consider documenting why rsc_table is placed at this specific offset
relative to m7_reserved.

Verify that the 1 MB vdevbuffer size is sufficient for the expected
virtio traffic between A55 and M7.

Ensure mu7 node is defined elsewhere in the base device tree; this
patch only enables it without defining its properties.
