----------------------------------------------------------------
SPI NOR changes for 6.19

Notable changes:

- Fix SMPT parsing for S25FS-S flash family. They report variable dummy cycles for reads. This results in the default of 0 being used. This works for other Infineon chips, but not for the S25FS-S family. They need 8 dummy cycles. Add fixup hooks to specify that. Also add fixup hooks to fix incorrect map ID data in SFDP.

- Add support for a bunch of Winbond flashes. Their block protection information is not discoverable, so they need to have an entry in the flash tables to describe that.

- Some cleanups for Micron flash support.

- Add support for Micron mt35xu01gbba.

- Some SPI controllers like the Intel one on the PCI bus do not support the read CR opcode (0x35). Do not use the opcode if the controller does not support it.

Hello Pratyush,

Just in case, the 'Subject:' mentions v6.18 ;)

Pulled into mtd/next, thanks a lot!

Copy-paste error :-)

I usually copy the last PR I sent and just bump the version numbers. Seems like I forgot this time.
