ASoC: dwc: fix support for more than two channels
There were missing break statements so everything used
TWO_CHANNEL_SUPPORT.
Also I added a return statement to silence a GCC warning:
sound/soc/dwc/designware_i2s.c: In function ‘dw_i2s_hw_params’:
sound/soc/dwc/designware_i2s.c:236:32: warning: ‘ch_reg’ may be
used uninitialized in this function
[-Wmaybe-uninitialized]
