Merge tag 'spi-nor/for-5.18' into mtd/next

SPI NOR core changes:
- move vendor specific code out of the core into vendor drivers.
- unify all function and object names in the vendor modules.
- make setup() callback optional to improve readability.
- skip erase logic when the SPI_NOR_NO_ERASE flag is set at flash
  declaration.
