[PATCH -queue 0/3] add CPUFreq support for loongson2f

[Wu Zhangjin <wuzhangjin@gmail.com>]

This patchset add CPUFreq support for loongson2f family machines, to untilize
this support, the machines need an external timer to ensure the system timer is
normal for the MIPS Timer's frequency is relative to the processor's frequency,
without an external timer, the system timer will be "mussy".

Thanks & Regards,
       Wu Zhangjin
