Wu Zhangjin f8ede0f700 MIPS: Loongson 2F: Add CPU frequency scaling support 
Loongson 2F supports CPU clock scaling. When put it into wait mode by
setting the frequency as ZERO it will stay in this mode until an external
interrupt wakes the CPU again.

To enable clock scaling support, an external timer of a known stable rate
is required.
