Winbond uses 3 bytes to identify flash: vendor_id, dev_id_0, dev_id_1, but current driver uses only first 2 bytes of it for devices identification. As result Winbond W25N02KV flash (id_bytes: EF, AA, 22) is identified as W25N01GV (id_bytes: EF, AA, 21).
Fix this by adding missed identification bytes.
