Infineon(Cypress) SEMPER NOR flash family has on-die ECC and its program
granularity is 16-byte ECC data unit size. JFFS2 supports write buffer
mode for ECC'd NOR flash. To activate it, MTD_BIT_WRITEABLE needs to be
unset in mtd->flags. In this series, a new SNOR_F_ECC flag is introduced
and fixups for SEMPER flash pats set it.

Changes in v3
  - Split to three patches

Changes in v2
  - Introduce SNOR_F_ECC flag
  - Add fixes tag and Cc stable
