[PATCH v16 6/8] mtd: spi-nor: Do not change nor->params->addr_nbytes at 4BAIT parsing time

[tkuw584924 at gmail.com]

From: Takahiro Kuwano <Takahiro.Kuwano at infineon.com>

At the 4BAIT parsing time, we need to keep nor->params->addr_nbytes value
as it may be used as current address mode in SMPT parse and device specific
hooks.
