sf: params: Add S25FS256S_64K spi flash support
Add Spansion S25FS256S_64K spi flash to the list of spi_flash_ids. In spansion S25FS-S family the physical sectors are grouped as normal and parameter sectors. Parameter sectors are 4kB in size with 8 set located at the bottom or top address of a device. Normal sectors are similar to other flash family with sizes of 64kB or 32 kB. To erase whole flash using sector erase(D8h or DCh) won't effect the parameter sectors, so in order to erase these we must use 4K sector erase commands (20h or 21h) separately. So better to erase the whole flash using 4K sector erase instead of detecting these family parts again and do two different erase operations.
