Revert "drm/amd/display: Pass HostVM enable flag into DCN3.1 DML"

This reverts commit 5e7c3bf06a45b42a835f48c41e0a00189cf91556.

While we were testing DCN3.1 with a hub, we noticed that only one of 2
connected displays lights up when using some specific display
resolution. In summary, this was the setup:

1. Displays:
 * Sharp LQ156M1JW26 (eDP): 1080@240
 * BENQ SW320 (DP): 4k@60
 * BENQ EX3203R (DP): 4k@60
2. Hub: Club3D CSV-7300
3. ASIC: DCN3.1

After bisecting this issue, we figured out the commit mentioned above
introduced this issue. We are investigating why this patch introduced
this regression, but we need to revert it for now.
