ASoC: Fix burstsize and DSP_B format problems in imx-ssi. 



When choosing IMX_DMA flag, burtsizes are set to its default
value (0) which leads to driver malfunction. Change them to 4.

DSP_B interface needs additional flag to match DSP_B formats
as described in several codecs as wm8741 and aic3205.
