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.

This patch adds basic options for MIPS CPUFreq support.
Since the cp0 timer's frequency is based on the processor clockrate it can
not be used with CPUFReq; an additional external timer is required.
