cpufreq: exynos4x12: Use the common clock framework to set APLL clock rate
In the exynos4x12_set_apll() function, the APLL frequency is set with
direct register manipulation.
Such approach is not allowed in the common clock framework. The frequency
is changed, but the corresponding clock value is not updated. This causes
wrong frequency read from cpufreq's cpuinfo_cur_freq sysfs attribute.
Also direct manipulation with PLL's S parameter has been removed. It is
already done at PLL35xx code.
Tested at:
- Exynos4412 - Trats2 board (linux 3.12-rc4)
