drm/radeon/cayman: set VM max pfn at MC init
No need to emit them at VM flush as we no longer use variable sized page tables now that we support 2 level page tables. This matches the behavior of SI (which does not support variable sized page tables). Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
