ENGR00219933 CS42888: abort delay powerdown if codec is on

CS42888 driver own 2 codec_dai for ESAI and ASRC P2P use. Due to the
delay power down mechanism, if a ASRC P2P stream is played right after
a finish of ESAI stream playback, ASRC P2P stream would be stop.

In this patch, do nothing in the delay powerdown flow if CS42888
codec is on.
