[PATCH v2 13/14] mtd: spinand: winbond: Rename cache op_variants struct variable

Till now, supported Winbond SPI NAND flashes had same supported
op_variants. W35N01JW introduces Octal DTR SPI IO mode, so now
different op_variants struct variables are required for different
Winbond flashes. Hence, rename and append the flash name in the
op_variants struct variable.
