[PATCH] cpufreq: tegra124: No need of setting platform-data

[Viresh Kumar]

All CPUs on Tegra platform share clock/voltage lines and there is
absolutely no need of setting platform data for 'cpufreq-dt' platform
device, as that's the default case.

Stop setting platform data for cpufreq-dt device.
