[PATCH 8/8] mtd: spi-nor: Move Spansion erase related fixup to a dedicated function

[Boris Brezillon <boris.brezillon@xxxxxxxxxxx>]

spi_nor_set_4byte_opcodes() is changing the erase size for Spansion
chips operating in 4B addressing mode. Let's move this code to
spansion_fixups() and call it from spi_nor_manufacturer_fixups().
