cpufreq-cpu0 driver can be probed over DT only if a corresponding device node is
created for the SoC which wants to use it. Lets create a platform device for
cpufreq-cpu0 driver for Tegra.
Also it removes the Kconfig entry responsible to compiling tegra-cpufreq driver
and hence there will not be any conflicts between two cpufreq drivers.
