[PATCH 4/5] mtd: spinand: winbond: fix flash identification

[Frieder Schrempf]

From: Mikhail Kshevetskiy <mikhail.kshevetskiy at iopsys.eu>

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.
