Merge tag 'spi-nor/for-5.9' of https://git.kernel.org/pub/scm/linux/kernel/git/mtd...

SPI NOR core changes:
- Disable Quad Mode in spi_nor_restore().
- Don't abort BFPT parsing when QER reserved value is used.
- Add support/update capabilities for few flashes.
- Drop s70fl01gs flash: it does not support RDSR(05h) which
  is critical for erase/write.
- Merge the SPIMEM DTR bits in spi-nor/next to avoid conflicts
  during the release cycle.

SPI NOR controller drivers changes:
- Move the cadence-quadspi driver to spi-mem. The series was
  taken through the SPI tree. Merge it also in spi-nor/next
  to avoid conflicts during the release cycle.
- intel-spi:
   - Add new PCI IDs.
   - Ignore the Write Disable command, the controller doesn't
     support it.
   - Fix performance regression.
