Macronix serial NAND flash with a two-plane structure
requires insertion of Plane Select bit into the column
address during the write_to_cache operation.
Additionally, for MX35{U,F}2G14AC, insertion of Plane
Select bit into the column address is required during
the read_from_cache operation.
These flashes have been validated on Xilinx zynq-picozed
board which included Macronix SPI Host.
