mtd: st_spi_fsm: Add support for Macronix MX25L3255E
This patch adds support for the Macronix MX25L3255E device. Unlike the other Macronix devices we have seen, this device supports WRITE_1_4_4 at reasonable frequencies. Rather than masking out WRITE_1_4_4 support altogether, we now rely on the table parameters to indicate whether or not WRITE_1_4_4 should be used.
