add RTC_LIB support for loongson family machines

The coming three patchs add RTC_LIB support for loongson family machines, which incorporated the feedback of the first patchset from Ralf and Arnaud Patard.

Hi, Paul Gortmaker or Alessandro Zummo, could you please help to apply the first two patches to linux-2.6.32?

And the third patch is for the queue branch of Ralf's -queue git repo.

Regards,
Wu Zhangjin
