sf: probe: Add support for S25FL* flash parts
Added S25FL* parts are which are avilable in spi_flash_probe_legacy.c. Updated the sector_size attributes as per the flash parts. Looks fine for with this sector_size for computing the size of flash. Signed-off-by: Jagannadha Sutradharudu Teki <jaganna@xilinx.com>
