ARM: tegra: dvfs: Add cold zone Tegra3 CPU dvfs limits

Added alternative frequency limits for Tegra3 CPU. These limits are
applied only in the lowest CPU EDP temperature zone, and the offset
from regular Tegra3 dvfs frequencies is set at -50MHz at all scaling
voltage steps. Offset values as well as temperature threshold are to
be updated per characterization.
