mtd: spinand: Add support for setting plane select bits

Browse Source 
Add two flags for inserting the Plane Select bit into the column
address during the write_to_cache and the read_from_cache operation.

Add the SPINAND_HAS_PROG_PLANE_SELECT_BIT flag for serial NAND flash
that require inserting the Plane Select bit into the column address
during the write_to_cache operation.

Add the SPINAND_HAS_READ_PLANE_SELECT_BIT flag for serial NAND flash
that require inserting the Plane Select bit into the column address
during the read_from_cache operation.
