ASoC: dapm: Make enable/disable_pin work with always on widgets
Always on widgets currently have some odd interactions with DAPM.
Enabling/disabling a widget (snd_soc_dapm_enable_pin) then connecting
it to a path works as expected, ie. when the widget is disabled the
path doesn't power up and it does when the widget is enabled. However
once in a path enabling the widget does not cause anything to power
up, dapm_widget_set_power will return the current power state of the
widget as 1, meaning we never check peer power states.
This patch updates dapm_always_on_check_power to return w->connected
such that it is effected by snd_soc_dapm_enable_pin and the like.
