ASoC: fsl: imx-pcm-rpmsg: Add SNDRV_PCM_INFO_BATCH flag
[ Upstream commit 2f9426905a63be7ccf8cd10109caf1848aa0993a ] The rpmsg pcm device is a device which should support double buffering. Found this issue with pipewire. When there is no SNDRV_PCM_INFO_BATCH flag in driver, the pipewire will set headroom to be zero, and because rpmsg pcm device don't support residue report, when the latency setting is small, the "delay" always larger than "target" in alsa-pcm.c, that reading next period data is not scheduled on time. With SNDRV_PCM_INFO_BATCH flag in driver, the pipewire will select a smaller period size for device, then the task of reading next period data will be scheduled on time.
