[PATCH 155/159] drm/amdgpu: Let KFD use more VMIDs on Aldebaran

From: Felix Kuehling <Felix.Kuehling at amd.com>

When there is no graphics support, KFD can use more of the VMIDs. Graphics
VMIDs are only used for video decoding/encoding and post processing. With
two VCE engines, there is no reason to reserve more than 2 VMIDs for that.
