drm/amd/display: Ignore UHBR13.5 cable ID cap for passive cable max link rate

Browse source

[Why]
Passive DP40 cables were updated in the latest DP spec to support
UHBR13.5 link rate. Current max link rate logic checks against the
cable ID DPCD even for passive cables.

[How]
Ignore UHBR13.5 cable ID DPCD cap in get_max_link_rate logic.
