drm/amd/display: use previous aux timeout val if no repeater.
[Why]
The aux timeout value is not default before reading link cap.
Setting it to default when lttpr is not enabled causes some monitor
not to light up.
[How]
Read the aux engine timeout value before setting it to extended.
Set the aux engine timeout to its previous value if no lttpr.
