Merge "ARM: tegra: Trusted Foundations work for 3.15" from Stephen Warren:

This pull request contains a number of cleanups and enhancements for the
Trusted Foundations firmware used on production Tegra SoCs. The changes
allow kernels without TF support to run on HW that uses TF, albeit with
reduced functionality, and also fix the cpuidle feature.
