Subject: [PATCH v4 00/11] mtd: spi-nor: spansion: Add support for Infineon S28HS02GT

v4:
- define vreg_offset for S25FS256T in the post_sfdp hook. The goal
is to use the same code base for both single and multi chip package
flashes.
- get rid of SPINOR_REG_CYPRESS_CFR{1,3,5}V as they are no longer used
