drm/amd/display: Update HPO I/O When Handling Link Retrain Automation Request
[WHY] Previous multi-display HPO fix moved where HPO I/O enable/disable is performed. The codepath now taken to enable/disable HPO I/O is not used for compliance test automation, meaning that if a compliance box being driven at a DP1 rate requests retrain at UHBR, HPO I/O will remain off if it was previously off. [HOW] Explicitly update HPO I/O after allocating encoders for test request.
