tegra124: Make the PLLX frequency selectable by model.
The PLLX provides the clock for the main cores which can run at different max
frequencies depending on the specific model of Tegra124. This change makes it
possible to select a model which will, in turn, select a frequency for PLLX.
The default is 2GHz which is the lowest maximum frequency.
BUG=chrome-os-partner:25467
TEST=Booted on nyan rev1. Verified that the selected PLLX frequency was 2GHz.
With a change that selects the right model for nyan, verified that the
corresponding frequency was selected.
BRANCH=None
