mtd: spinand: esmt: Extend IDs to 5 bytes
[ Upstream commit 4bd14b2fd8a83a2f5220ba4ef323f741e11bfdfd ] According to the datasheets, the ESMT chips in question will return a 5 byte long identification code where the last 3 bytes are the JEDEC continuation codes (7Fh). Although, I would have expected 4 continuation codes as Powerchip Semiconductor (C8h, corresponding to the parameter page data) is located in bank 5 of the JEDEC database. By matching the full 5 bytes we can avoid clashes with GigaDevice NAND flashes. This fix allows the MT7688-based GARDENA smart Gateway to boot again.
