During resume, DP uses AUX to perform various functionalities
like DPCD/EDID read or link training etc. This involves other
hardware modules as well like USB and Charger. In a situation
like continuous suspend/resume, while DP is processing resume,
suspend can trigger resulting in dependent hardware modules
to go to sleep. As AUX communication is hardware interrupt
based, this can result in unstable system.
Abort all functionalities before going to suspend to
avoid unnecessary AUX and other functionality failures.

DP debug module is run by external script for automation testing.
DP aux and debug modules operate on shared buffers. In some race
conditions, aux and debug module can go out of sync resulting in
automation failures. Lock the buffers to make sure there are no
race conditions.
