[PATCH v10 6/6] mtd: spi-nor: add support for Macronix Octal flash

From: AlvinZhou <alvinzhou at mxic.com.tw>

Adding manufacturer ID 0xC2 at the end of ID table
to allow manufacturer fixup to be applied for any
Macronix flashes instead of needing to list each
flash ID in the ID table.

Such as macronix_nor_set_octal_dtr function in the
manufacturer fixup can be applied to any Macronix
Octal Flashes without the need to add the specific
ID in the ID table.
