ARM: S5PV210: Add struct clk_ops for clk_fout_apll
Current fout_apll has fixed rate value. So CPUFREQ driver gets incorrect value when finding current CPU frequency. Because some operation level need to change APLL. Added get_rate function for fout_apll can give correct frequency value when calling get_rate function.
