If the device is runtime suspended the eDP panel power is also off. Ignore a short HPD on eDP if the device is suspended accordingly, instead of checking the panel power state via the PPS registers for the same purpose. The latter involves runtime resuming the device unnecessarily, in a frequent scenario where the panel generates a spurious short HPD after disabling the panel power and the device is runtime suspended.
