Tegra has a micro-second counter whose rate doesn't vary with cpufreq
changes. Register it so it can be used as the delay timer, so delays
aren't influenced by cpufreq.
I've made this a separate branch since it touches a few files outside
arch/arm/mach-tegra/. This can be merged anywhere that conflicts need
to be resolved, although I know of no such places at present.
