Subject: [PATCH] mtd: maps: Allow MTD_PHYSMAP with MTD_RAM

When the physmap_of_core.c code was merged into physmap-core.c the
ability to use MTD_PHYSMAP_OF with only MTD_RAM selected was lost.
Restore this by adding MTD_RAM to the dependencies of MTD_PHYSMAP.

Fixes: commit 642b1e8dbed7 ("mtd: maps: Merge physmap_of.c into physmap-core.c")
