ARM: tegra: common device resources

Add a common location to register resources for used on-chip devices
that are commonly configured on boards. Devices will be added to this file
as more drivers are added that can make use of them.

This is based on work contributed by several people, most of it from
Colin Cross and Erik Gilling.
