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.
