[PATCH] spi: synquacer: remove SPI_TX_BYTE handling

[Masahisa Kojima]

Current code expects that SPI_TX_BYTE is single bit mode
but it is wrong. It indicates byte program mode,
not single bit mode.

If SPI_TX_DUAL, SPI_TX_QUAD and SPI_TX_OCTAL bits are not set,
the default transfer bus width is single bit.
