Next up would be to wire up the DP hotplug pin to speed up panel power sequencing for eDP panels ... I've decided to leave the has_aux_irq logic in the code, it should come handy for hw bringup. For testing/fail-safety the dp aux code already has a timeout when waiting for interrupts to signal completion and screams rather loud if they don't arrive in time. Given that we need a real piece of hw to talk to anyway this is probably as good as it gets. v2: Don't check the dp aux channel bits on i965 machines, they have a different meaning there. Yay for reusing bits at will! Spotted by Jani.
