This function is called indirectly by intel_crtc_compute_config(),
which needs to be converted to work only with an atomic state.

I'm not sure what are the implications of ignoring intel_crtc->active in
pipe_has_enabled_pch(). If we allow a config because the third pipe is
enabled but not active, wouldn't we run into trouble when we tried to
activate the crtc?
