[PATCH 1/9] mtd: spi-nor-core: Clean up macros for Infineon(Cypress) S25 and S28

[tkuw584924 at gmail.com]

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

Some macro definitions used in Infineon(Cypress) S25 and S28 series are
redundant and some have inconsistent prefix. This patch removes redundant
ones and renames some to have same prefix as others.
