PM / devfreq: tegra: add devfreq driver for Tegra Activity Monitor
The ACTMON block can monitor several counters, providing averaging and firing interrupts based on watermarking configuration. This implementation monitors the MCALL and MCCPU counters to choose an appropriate frequency for the external memory clock. This patch is based on work by Alex Frid <afrid@nvidia.com> and Mikko Perttunen <mikko.perttunen@kapsi.fi>.
