Eric Yang a4d5df1787 drm/amd/display: add workaround for riommu invalidation request hang
[Why]
When an riommu invalidation request come at the same time as a pipe is
disabled there can be a case where DCN cannot ACK the request if only
one VMID is setup in the inuse list.

[How]
Setup a second unused VMID will work around the issue.
