sna: Enable TearFree by default on recent HW

When there is ample memory bandwidth and we are not fighting for global
resources, enable TearFree by default. Avoiding tearing is much more
pleasant (for direct rendering where the source itself is not being
synchronized to vblank) at negligible power cost; just doubles the
memory footprint of scanout.
