[PATCH] drm/amd/display: Disable HPD filter for HDMI

This is a bit of a shot in the dark but I'm curious if HPD filtering causes us
to lose the HPD signal for some reason.

Do you have a chance to try this patch and see if it fixes the issue?

Note: This patch is really only for debug purposes and might lead to other
instability with display detection.
