Subject: drm/amdgpu: Ignore the not supported error from psp
Git-commit: d73cd701278a04a55e41fa0d094aed492720d551
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

As the VCN firmware will not use
vf vmr now. And new psp policy won't support set tmr
now.
For driver compatible issue, ignore the not support error.
