ASoC: cs35l56: Increase pm_runtime autosuspend delay

Browse Source 
Increase the pm_runtime autosuspend delay to be longer than the
timeout of the firmware's own inactivity timer.

There is no point attempting to pm_runtime suspend any sooner than
the firmware idle timeout because it would only mean the driver has
to poll waiting for the firmware idle.
