Power change event like stream start/stop or kcontrol change in a cross-device path originates from one device but codec bias and widget power changes must be populated to another devices on that path as well. This patch modifies the dapm_power_widgets so that all the widgets on a sound card are checked for a power change, not just those that are specific to originating device. Also bias management is extended to check all the devices. Only exception in bias management are widgetless codecs whose bias state is changed only if power change is originating from that context. DAPM context test is added to dapm_seq_run to take care of if power sequence extends to an another device which requires separate register writes.
