Merge tag 'tegra-for-3.8-cpuidle' of git://git./linux/kernel/git/swarren/linux-tegra into next/soc

From Stephen Warren:
ARM: tegra: cpuidle enhancements

A cpuidle state "LP2" is added, which power-gates the CPUs. Support for
CPUs 1..n is essentially complete, although support for CPU0 could
benefit from future use of coupled-cpuidle or similar techniques.

A couple of very minor cleanups to cpuidle were included too.

This pull request is based on tegra-for-3.8-soc.
