Revert "drm/amd/display: Pass HostVM enable flag into DCN3.1 DML"
This reverts commit 863fa85e6a01c8b239009825dd9de1f64d7d020a.
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.
