In the latest JEDEC standard (JESD216F), there are now bitfields in the
4 byte address instruction table for 1S-1S-8S and 1S-8S-8S modes

This patchset adds support for checking the 4BAIT for these modes,
along with additional NO_SFDP_FLAGS to support enabling these new modes

Nathan Barrett-Morrison (3):
  mtd: spi-nor: Extend SFDP 4byte address instruction lookup table with
    new octal modes as per JEDEC JESD216F
  mtd: spi-nor: Add additional octal-mode flags to be checked during
    SFDP
  mtd: spi-nor: Add support for IS25LX256 operating in 1S-1S-8S mode
