Merge tag 'spi-nor/for-6.4' into mtd/next

SPI NOR core changes:
* introduce Read While Write support for flashes featuring several banks
* set the 4-Byte Address Mode method based on SFDP data
* allow post_sfdp hook to return errors
* parse SCCR MC table and introduce support for multi-chip devices

SPI NOR manufacturer drivers changes:
* macronix: add support for mx25uw51245g with RWW
* spansion:
  - determine current address mode at runtime as it can be changed in a
    non-volatile way and differ from factory defaults or from what SFDP
    advertises.
  - enable JFFS2 write buffer mode for few ECC'd NOR flashes: S25FS256T,
    s25hx and s28hx
  - add support for s25hl02gt and s25hs02gt
