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.
