Boris Brezillon 13c15e07ee mtd: spinand: Handle the case where PROGRAM LOAD does not reset the cache 
Looks like PROGRAM LOAD (AKA write cache) does not necessarily reset
the cache content to 0xFF (depends on vendor implementation), so we
must fill the page cache entirely even if we only want to program the
data portion of the page, otherwise we might corrupt the BBM or user
data previously programmed in OOB area.
