mtd: spinand: esmt: Extend IDs to 5 bytes
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.
