mips: loongsoon2ef: remove private clk api
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.
