of_mtd: Add no-op stubs to support CONFIG_OF=n
Just like the rest of the subsystems, let's add the required no-op
functions to implement stubs when CONFIG_OF=n.
This prevents MTD drivers from having ugly ifdefs in their code,
and instead hide the ifdef monster in the header closet (far away
from people's sight).
