drm/amd/display: Disable GPUVM in IP resource configuration

[Why]
VM enabled in IP configuration causes UCLK not
reaching DPM0. The expectation for VM enable should
be that KMD will indicate to DAL when VM is enabled,
then DAL will set the bit accordingly

[How]
Set gpuvm_enable to zero in DCN3_20 and DCN3_21 resource.
