mtd: spi-nor: spansion: Enable JFFS2 write buffer for Infineon s25hx …
…SEMPER flash [ Upstream commit 4199c17 ] 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. Provide a way to clear the MTD_BIT_WRITEABLE flag in order to enable JFFS2 write buffer mode support.
