soc-pcm's dpcm_fe_dai_do_trigger() supported DRAIN commnad up to kernel v5.4 where explicit switch(cmd) has been introduced which takes into account all SNDRV_PCM_TRIGGER_xxx but SNDRV_PCM_TRIGGER_DRAIN. Update switch statement to reactive support for it.
As DRAIN is somewhat unique by lacking negative/stop counterpart, bring behaviour of dpcm_fe_dai_do_trigger() for said command back to its pre-v5.4 state by adding it to START/RESUME/PAUSE_RELEASE group.
