Review Comment:
If the MTD driver implements the markbad and isbad and is not a NAND driver
(NAND drivers already select it by default), it can also "select" it by the
same configuration flag which enables that driver, to avoid misconfiguration.
We definitely don't want to set it for all MTD_PARTITIONs, because it is
very rare case when it is needed. That would void the purpose of the whole
flag. There are only a few drivers which need the bad block management, and for
all the others it is only dead weight.
