sf: Enable byte program support
Enabled byte program support for sst flashes in sf. Few controllers will only support BP, so this patch gives a tx transfer flag to set the BP so-that sf will operate on byte program transfer. A new TX operation mode SPI_OPM_TX_BP is introduced for such SPI controller to use byte program op for SST flash.
