ASoC: imx-pcm-rpmsg: Fix warning of incorrect type in assignment 

The format in rpmsg is defained as unsigned char, there is warning
when convert snd_pcm_format_t to it.

sound/soc/fsl/imx-pcm-rpmsg.c:164:43: sparse: warning: incorrect type in assignment (different base types)
sound/soc/fsl/imx-pcm-rpmsg.c:164:43: sparse:    expected unsigned char format
sound/soc/fsl/imx-pcm-rpmsg.c:164:43: sparse:    got restricted snd_pcm_format_t [usertype]
sound/soc/fsl/imx-pcm-rpmsg.c:167:43: sparse: warning: incorrect type in assignment (different base types)
sound/soc/fsl/imx-pcm-rpmsg.c:167:43: sparse:    expected unsigned char format
sound/soc/fsl/imx-pcm-rpmsg.c:167:43: sparse:    got restricted snd_pcm_format_t [usertype]

Refine the unused RPMSG_DSD_U16_LE and RPMSG_DSD_U32_LE for these
case to fix this sparse warning.
