I would have implemented this by "if (!cpu_class_is_omap1())
{..._burst_mode}" for making sure that no new OMAP1 error is introduced
in the future if there is need to add some common stuff after those
burst_mode calls and probably compiler can better optimize away those
burst_mode calls for OMAP1 builds.
