MLK-14582: ASoC: imx-pcm-rpmsg: fix audio noise issue with pulseaudio

The pulse audio will set a wrong buffer size which is not the integral
multiple of period size, it will cause the DMA can't work correctly in
M4 side.
The reason is that we always need to add a constraint for
SNDRV_PCM_HW_PARAM_PERIODS, which make it integer.
