generic: spi-nor: fix 4-byte opcode support for w25q256

There are 2 different chips (w25q256fv and w25q256jv) that share
the same JEDEC ID. Only w25q256jv fully supports 4-byte opcodes.
Use SFDP header version to differentiate between them.

Fixes broken reboot on 8devices Habanero since f0f35fdac
