ARM: S3C24XX: cpufreq-utils: don't write raw values to MPLLCON when using ccf
The s3c24xx cpufreq driver needs to change the mpll speed and was doing this by writing raw values from a translation table into the MPLLCON register. Change this to use a regular clk_set_rate call when using the common clock framework and only write the raw value in the samsung_clock case. The s3c cpufreq driver does already aquire the mpll, so simply add a reference to struct s3c_cpufreq_config to let set_fvco access it. While struct clk is opaque the differenciation between samsung clock and common clock is kept, as the samsung-clock mpll clk does not implement a real set_rate.
