drm/amd/display: Fix system hang while resume with TBT monitor
[Why]
Connected with a Thunderbolt monitor and do the suspend and the system
may hang while resume.
The TBT monitor HPD will be triggered during the resume procedure
and call the drm_client_modeset_probe() while
struct drm_connector connector->dev->master is NULL.
It will mess up the pipe topology after resume.
[How]
Skip the TBT monitor HPD during the resume procedure because we
currently will probe the connectors after resume by default.
