ARM: tegra: power: Add CPU EDP support

CPU electrical design point (EDP) limits specify maximum CPU frequency
depending on number of CPU cores on-line, and chip temperature. This
commit added initial edp governor to cpufreq driver. Governor is aware
of CPU departure/arrival, but temperature dependency is yet to be added.
Therefore CPU EDP support is left disabled for now.
