Merge tag 'spi-nor/for-6.2' into mtd/next

SPI NOR core changes:
* Add support for flash reset using the dt reset-gpios property.
* Update hwcaps.mask to include 8D-8D-8D read and page program ops
  when xSPI profile 1.0 table is defined.
* Bypass zero erase size in spi_nor_find_best_erase_type().
* Fix select_uniform_erase to skip 0 erase size
* Add generic flash driver. If a flash is not found in the flash_info
  array, fall back to the generic flash driver which is described solely
  by the flash's SFDP tables.
* Fix the number of bytes for the dummy cycles in
  spi_nor_spimem_check_readop().
* Introduce SPI_NOR_QUAD_PP flag, as PP_1_1_4 is not SFDP discoverable.

SPI NOR manufacturer drivers changes:
* Spansion:
  - use PARSE_SFDP for s28hs512t,
  - add support for s28hl512t, s28hl01gt, and s28hs01gt.
* Gigadevice: Replace default_init() with post_bfpt() for gd25q256.
* Micron - ST: Enable locking for mt25qu256a.
* Winbond: Add support for W25Q512NW-IQ.
* ISSI: Use PARSE_SFDP and SPI_NOR_QUAD_PP.

Fix merge conflict in the jedec,spi-nor bindings.
