drm/amd/display: check for repeater when setting aux_rd_interval.
[Why]
When training with repeater the aux read interval must be set to
repeater specific aux_red_interval. This value is always 100us for CR.
[How]
Check for repeater when setting the aux_rd_interval in channel
equalization.
Use the right offset in the aux_rd_interval array
