[libcpu] mips: Merge loongson_1 into gs232

2019-12-11T07:24:42Z

Previously Loongson 1B and Loongson 1C have their own libcpu implemention, but they're almost identical. So we merge them into gs232 and adapt to new common code. Signed-off-by: Jiaxun Yang

[libcpu] Refine MIPS common code

2019-12-11T07:24:04Z

MIPS common code was highly duplicated, This commit is a attempt to clean-up and refine these code. The context and exception handle flow is mostly identical with Linux, but a notable difference is that when FPU enabled, we save FP registers in stackframe unconditionally.
