drm/amd/display: Increase idle worker HPD detection time

Browse Source 
[ Upstream commit 60612f75992d96955fb7154468c58d5d168cf1ab ]

[Why]
Idle worker thread waits HPD_DETECTION_TIME for HPD processing complete.
Some displays require longer time for that.

[How]
Increase HPD_DETECTION_TIME to 100ms.
