Subject: [PATCH 2/2] mtd: spi-nor: disable 16-bit-sr for macronix

Macronix flash chips seem to consist of only one status register.
These chips will not work with the "16-bit Write Status (01h) Command".
Disable SNOR_F_HAS_16BIT_SR for all Macronix chips.

Tested with MX25L6405D.

Fixes: 39d1e3340c73 ("mtd: spi-nor: Fix clearing of QE bit on
lock()/unlock()")
