drm/amdgpu: disable gpu-sched load balance for uvd_enc
On hardware with multiple uvd instances, dependent uvd_enc jobs
may get scheduled to different uvd instances. Because uvd_enc
jobs retain hw context, dependent jobs should always run on the
same uvd instance. This patch disables GPU scheduler's load balancer
for a context that binds jobs from the same context to a uvd
instance.
