[PATCH v3 04/23] mtd: spi-nor: Add support for the new JESD216 rev F QER field

[Takahiro.Kuwano at infineon.com]

> Revision F of the JEDEC JESD216 standard includes yet another
> supported setting in the QER 3-bit bitfield: 110b.
> 
> This setting implies that the QE bit is bit 1 of SR2 (which is an
> already supported case) but this time it makes it very clear that both
> reading and writing to SR2 is supported, but not with the usual
> opcodes. The write operation uses an alternate WRSR2 opcode:
> 0x31 (instead of 0x3E) and both the reads and writes manipulate a single
> register at a time.
