MIPS: Loongson: Split common loongson source code out
To share common loongson source code between all of the loongson-based machines. there is a need to split it out of the fuloong-2e/ directory. at the same time, other according tuning is needed. the machine-specific parts are defined as macros in relative header file, pci.h, mem.h, machine.h.
