drm/amd/display: extending AUX SW Timeout
[Why] AUX takes longer to reply when using active DP-DVI dongle on some asics resulting in up to 2000+ us edid read (timeout). [How] 1. Adjust AUX poll to match spec 2. Extend the SW timeout. This does not affect normal operation since we exit the loop as soon as AUX acks.
