ARM: tegra12: dvfs: Support variable GPU Vmin
Replaced constant GPU minimum voltage limit with variable Vmin
adjusted based on particular chip speedo value and temperature range.
CVB polynomial equation used for Vmin calculation is the same as for
each GPU DVFS frequency, just coefficients are different. Still apply
absolute Vmin at cold (below 15C) to GPU rail for the entire Tegra12
family.
