Subject: [PATCH 2/2] cpufreq: tegra124: Allow building as a module

From: Aaron Kling <webgeek1234@...il.com>

This requires a soft dependency on cpufreq-dt as this driver only
handles power management and cpufreq-dt does the real operations. Other
than that, this works fine as a module, so allow building as such.
