It might be better to create <linux/tegra-cpufreq.h> for the interface
to the cpufreq driver; tegra-soc.h is for the interface to core Tegra
code *from* other drivers.

Probably best to "return 0" from the !CONFIG_ARM_TEGRA_CPUFREQ case; the
whole point is to isolate callers from having to care whether
CONFIG_ARM_TEGRA_CPUFREQ is enabled, and making the function act like it
worked OK is part of that isolation.
