MLK-22340-5: ASoC: imx-pcm-rpmsg: enable ignore_suspend for LPA

Browse Source 
In LPA drain state, if runtime->status->state is SUSPEND, after resume,
ALSA would exit drain mode directly, that cause some data in end
of song is missed.

This patch is to enable ignore_suspend flags that
the runtime->status->state will be not in SUSPEND always.
