At pm_resume check link sisnk_count before update is_connected status
base on HPD real time link status. Also print out error message only
when either EV_CONNECT_PENDING_TIMEOUT or EV_DISCONNECT_PENDING_TIMEOUT
happen.

At dp_display_disable(), do not re initialize audio_comp if
hdp_state == ST_DISCONNECT_PENDING (unplug event) to avoid
race condition which cause 5 second timeout expired. Also
add abort mechanism to reduce time spinning at dp_aux_transfer()
during dpcd read if type-c connection had been broken.

They were reading a counter that was configured to ALWAYS_COUNT (ie.
cycles that the GPU is doing something) rather than ALWAYS_ON. This
isn't the thing that userspace is looking for.
