mixer_regs_dump() was called in mixer_run(), which was called
under the register spinlock in mixer_graph_buffer() and
vp_video_buffer().

This would trigger a sysmmu pagefault with drm.debug=0xff because
of the large delay caused by the register dumping.

To keep consistency also move register dumping out of mixer_stop(),
which is the counterpart to mixer_run().
