[PATCH v2 2/2] mtd: spi-nor-core: Make CFRx reg fields generic

[tkuw584924 at gmail.com]

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

Cypress defines two flavors of configuration registers, volatile and
non volatile, and both use the same bit fields. Rename the bitfields in
the configuration registers so that they can be used for both flavors.
