MIPS: Fork loongson2ef from loongson64
As later model of GSx64 family processors including 2-series-soc have similar design with initial loongson3a while loongson2e/f seems less identical, we separate loongson2e/f support code out of mach-loongson64 to make our life easier. This patch contains mostly file moving works.
