dummyflasher.c: Remove custom mapper from opaque_master

Dummy doesn't need a custom mapper on opaque_master; the returned
address is not used and the mapper has no side effects.

This is the only remaining opaque master with a custom mapper, so this
permits removing custom mapper support from opaque masters.
