snd_soc_4_12_spi_write swaps the upper and the lower byte of the to be transferred data. The function was added for the ad1836, which was used in 16bit mode on the blackfin boards. In this mode the blackfin SPI core swaps the upper and the lower byte before putting them on the wire (i.e interprets the word as litte-endian), so the data had to be passed in reversed, so it would appear in correct order on the wire. Since this behaviour not necessarily applicable to other configurations remove the special case.
The blackfin boards using the ad1836 were changed to used 8-bit mode in the previous commit.
