drm/amd/display: Assume an LTTPR is always present on fixed_vs links
[WHY]
LTTPRs can in very rare instsances fail to increment DPCD LTTPR count.
This results in aux-i LTTPR requests to be sent to the wrong DPCD
address, which causes link training failure.
[HOW]
Override internal repeater count if fixed_vs flag is set for a given link
