Sankeerth Billakanti 766b43bd13 disp: msm: dp: remove link probe from dp display driver ...

When resuming the video session from a source initiated power down, the
dp_display driver is doing a link probe again to override the previous
link information parameters. The link_probe is not accurately capturing
all the sink capabilities resulting in the link getting trained at a
different rate when resuming from a PM suspend or a secure display
session. The HBR3 support is indicated in the extended capabilities
DPCD registers which is not considered in the upstream link probe
implementation.

This change will remove the drm_dp_link_probe function from the DP
driver because it is not capturing the accurate DP sink capabilities.
