Is the Tegra114 APBMISC register layout 100% a backwards-compatible
superset of that in Tegra20? For both registers the code currently uses
*and* all possible registers the code could ever use? Since the APB MISC
is a bit of a dumping ground for random registers, that feels unlikely,
but perhaps it's possible.
