Upon failure to probe the DFLL, the OPP table will not be cleaned up
properly. Fix this and while at it make sure the OPP table will also be
cleared upon driver removal.

Rename some variables and structure fields to make the code more
comprehensible. Also change the prototype of internal functions to be
more in line with the OPP core functions.

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.
