MLK-21107-1: ASoC: Fix timer wake up system after suspend

Browse Source 
Fixes commit 4028bd0f76 ("MLK-21002-2: ASoC: imx-pcm-rpmsg: don't
remove timer at suspend")

if the timer isn't removed at suspend, there will be interrupt
from M4 side when the period size is small to wake up system quickly
So we need to revert the previous fix and add timer in resume state
