Subject: [PATCH] mtd: rawnand: Fix JEDEC detection

nand_jedec_detect() should return 1 when the PARAM page parsing
succeeds, otherwise the core considers JEDEC detection failed and falls
back to ID-based detection.

Fixes: 480139d9229e ("mtd: rawnand: get rid of the JEDEC parameter page in nand_chip")
