[PATCH v3 00/25] mtd: spi-nor: Clean params init

[Tudor Ambarus]

Clean spi_nor_scan() and the flash parameters initialization code. 
Tested all the flashes from patch set. If someone can test the
locking ops on few flashes would be great. It seems that my flashes
have the non volatile bits weared out.

This patch set is split from:
https://lore.kernel.org/linux-mtd/20210727045222.905056-1-tudor.ambarus@microchip.com/
The ID collision series will be set in a dedicated patch set that will
depend on this one.

Changes in v3:
- move late_init() in struct spi_nor_fixups and update patches accordingly.     
R-b tags were dropped.
- new patch "mtd: spi-nor: sst: Get rid of SST_WRITE flash_info flag"
moves manufacturer specific flag out of the core.
- update methods description to make it clear who sets when
- introduce flash_info flag masks to make it clear when one should be set.
- rework "parse SFDP first idea".
