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.
