commit 6792b7fce610bcd1cf3e07af3607fe7e2c38c1d8 upstream.
When the exact mapping type driver was not available, the old
physmap_of_core driver fell back to mapping the region as ROM.
Unfortunately this feature was lost when the DT and pdata cases were
merged. Revive this useful feature.
Fixes: 642b1e8dbed7bbbf ("mtd: maps: Merge physmap_of.c into physmap-core.c")
