mtd: spi-nor: winbond: Add support for W25Q32RV-Q/N
There is an ID collision with the chip of same density from the JV
family. Both chips are very similar in practice, it is mostly a matter
of electrical differences (mostly power consumption being lower).
As a significant difference, RV chips identify themselves as supporting
the new SFDP (rev F) field which forces an alternate write SR2
opcode (0x31).
