[Greg Kroah-Hartman]

From: Sherry Wang <Yao.Wang1@xxxxxxx>

[ Upstream commit 796d6a37ff5ffaf9f2dc0f3f4bf9f4a1034c00de ]

[Why]
Hostvm should be enabled/disabled accordding to
the status of riommu_active, but hostvm always
be disabled on DCN31 which causes underflow

[How]
Set correct hostvm flag on DCN31
