MIPS: add initial Loongson-based boards support 

Loongson (simplified Chinese: 龙芯; pinyin: Lóngxīn; literally: "Dragon Core")
is a family of general-purpose MIPS CPUs developed at the Institute of Computing
Technology (ICT), Chinese Academy of Sciences (CAS) in the People's Republic of China.

See http://en.wikipedia.org/wiki/Loongson for details.
