Commit 52ba67b ("ASoC: Force all DAPM contexts into the same bias state") powers up all the DAPM contexts in a card if any DAPM context becomes active. Unfortunately power down newer happens if per-card DAPM context doesn't have any widgets.

Reason for this is that power state of per-card DAPM context without widgets is never cleared and thus all the DAPM contexts remain permanently active. Test for widgetless calling DAPM context in dapm_power_widgets() doesn't work for per-card DAPM context since power change is never originating from widgetless per-card DAPM context.

Fix this by pre-clearing power state flag of non-codec DAPM context at the beginning of power sequence.
