As platforms are moving to COMMON_CLK in general, loongson2ef stuck out as something that has a private implementation but does not actually use it except for setting the frequency of the CPU itself from the loongson2_cpufreq driver. Change that driver to call the register setting function directly and remove the rest of the stub implementation.

This option enables the mfgpt0 timer of AMD CS5536. With this timer

switched on you can not use high resolution timers.

If you want to enable the Loongson2 CPUFreq Driver, Please enable

this option at first, otherwise, You will get wrong system time.
