* [PATCH v2] cpufreq: scpi: Depend on SCPI clk driver

The SCPI clk driver registers the virtual cpufreq device that kicks off
initialisation of the SCPI cpufreq driver. Also, clk_get() will fail for
the cpufreq driver if the scpi clk driver is missing.

Fix this by making the scpi cpufreq driver explicitly depend on the scpi
clk driver.
