w25.c: enable support for W25QxxxJV NOR flash memories 

W25QxxxJV NOR memories are backward compatible with older Winbond´s
generations and thus can also be supported here. This essentially brings
the support for generic SPI to W25QxxxJV memories as w25qxxxjv.c file only
supports QSPI communication.
