Technically this changes the name of the driver. Sometimes boot or other
scripts rely on those names. Perhaps a better way of keeping backwards-
compatibility would be to do:

	obj-$(CONFIG_ARM_TEGRA_DEVFREQ)		+= tegra-devfreq.o
	tegra-devfreq-y				+= tegra30-devfreq.o

That way you can later on just add the tegra20-devfreq.o to that driver
as well and have them both ship in one .ko.
