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.
