[PATCH v4 04/13] mtd: rawnand: mxc: remove useless checks in GET/SET_FEATURES functions

All the calls to the chip's hooks ->get/set_features() go through
the core's wrappers nand_get/set_features() that already do the
necessary checks about feature support. Remove these
checks from the mxc's functions.
