Subject: [PATCH] devfreq: tegra20: add COMMON_CLK dependency

Compile-testing the new driver on platforms without CONFIG_COMMON_CLK
leads to a link error:

drivers/devfreq/tegra20-devfreq.o: In function `tegra_devfreq_target':
tegra20-devfreq.c:(.text+0x288): undefined reference to `clk_set_min_rate'

Add a dependency on COMMON_CLK to avoid this.

Fixes: 1d39ee8dad6d ("PM / devfreq: Introduce driver for NVIDIA Tegra20")
