Commit c4e8862308d4 (mtd: spi: Switch to new SPI NOR framework)
performs switch from previous 'spi_flash' infrastructure without
proper testing/investigations which results in a regressions for
SST26 flash series.

Enable protection ops for SST26 flash series which were
previously enabled by
Commit 3d4fed87a5fa (mtd: sf: Add support of sst26wf* flash ICs
protection ops)
