Subject: [PATCH 076/113] mtd: spi-nor: drop unnecessary partition parser data

Now that the SPI-NOR/MTD framework pass the 'flash_node' through to the
partition parsing code, we don't have to do it ourselves.

Also convert to mtd_device_register(), since we don't need the 2nd and
3rd parameters anymore.
