drm/amd/display: Reduce HPD Detection Interval for IPS

Browse source

Fix DP Compliance test 4.2.1.3, 4.2.2.8, 4.3.1.12, 4.3.1.13
when IPS enabled.

Original HPD detection interval is set to 5s which violates DP
compliance.
Reduce the interval parameter, such that link training can be
finished within 5 seconds.
