Upon detecting the ID for the ESMT F50D1G41LB chip, the fifth byte
returned is always 0x00 instead of the expected JEDEC continuation code
of 0x7f. This causes detection to fail:
[ 0.304399] spi-nand spi0.0: unknown raw ID c8117f7f00
[ 0.508943] spi-nand: probe of spi0.0 failed with error -524
So let's revert back to the 4 byte ID code for this chip
specifically.
Fixes: 4bd14b2fd8a8 ("mtd: spinand: esmt: Extend IDs to 5 bytes")
