Subject: [PATCH v9 2/2] mtd: spi-nor: fix nor->addr_width for is25wp256

Use the post bfpt fixup hook for the is25wp256 device as done for
is25lp256 device to overwrite the address width advertised by BFPT.

For instance the standard devices eg: IS25WP256D-JMLE where J stands
for "standard" does not support SFDP.
