[PATCH v2 5/6] mtd: spi-nor: Add s3an_post_sfdp_fixups()

[<Tudor.Ambarus@microchip.com>]

From: Tudor Ambarus <tudor.ambarus@microchip.com>

s3an_nor_scan() was overriding the opcode selection done in
spi_nor_default_setup(). Set nor->setup() method in order to
avoid the unnecessary call to spi_nor_default_setup().
