clk: tegra: Add functions for parsing CVB tables
Tegra CVB tables encode the relationship between operating voltage and optimal frequency as a function of the so-called speedo value. The speedo value is written to the on-chip fuses at the factory, which allows the voltage-frequency operating points to be calculated on an per-chip basis. Add utility functions to parse the Tegra-specific tables and export the voltage-frequency pairs to the generic OPP framework for other drivers to use.
