ls102xa: audio: Workaround for SAI data transfer endian issue
Transmit Data Register(TDR) used as the destination address
of EDMA transaction is in big-endian mode. The audio data in
memory and EDMA transaction are in little-endian mode. For
S16_LE format data, a workaround is to swap the original 16-bit
data, and then write into the higher 16 bit of TDR.
