mtd: spinand: macronix: Flag parts needing explicit plane select
Macronix serial NAND flash with a two-plane structure requires
insertion of the Plane Select bit into the column address during
the write_to_cache operation.
Additionally, for MX35{U,F}2G14AC and MX35LF2GE4AB, insertion of
the Plane Select bit into the column address is required during
the read_from_cache operation.
