Power up the ASTDP connector for connection status detection if the
connector is not active. Keep it powered if a display is attached.
This fixes a bug where the connector does not come back after
disconnecting the display. The encoder's atomic_disable turns off
power on the physical connector. Further HPD reads will fail,
thus preventing the driver from detecting re-connected displays.
For connectors that are actively used, only test the HPD flag without
touching power.
