[GIT PULL 3/3] ARM: tegra: use us counter as delay timer

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.


The following changes since commit 7171511eaec5bf23fb06078f59784a3a0626b38f:

  Linux 3.16-rc1
