Atm, we refcount both power domains and power wells and intel_display_power_enabled_sw() returns the power domain refcount. What the callers are really interested in though is the sw state of the underlying power wells. Due to this we will report incorrectly that a given power domain is off if its power wells were enabled via another power domain, for example POWER_DOMAIN_INIT which enables all power wells. As a fix return instead the state based on the refcount of all power wells included in the passed in power domain.
