drm/amd/display: Fix reduced resolution and refresh rate
[WHY]
Some monitors are forced to a lower resolution and refresh rate after
system restarts.
[HOW]
Some monitors may give invalid LTTPR information when queried such as
indicating they have one DP lane instead of 4. If given an invalid DPCD
version, skip over getting lttpr link rate and lane counts.
