sf: probe: Add support for SST_WP
Most of the SST flashes needs to write up using SST_WP, AAI Word Program, so added a flag param on spi_flash_params table. SST flashes, which supports SST_WP need to use a WP write sst_write_wp instead of common flash write. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>
