Jiaxun Yang 9ef986929c [libcpu] mips: Merge loongson_1 into gs232 
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.

Jiaxun Yang 7c66501861 [libcpu] Refine MIPS common code 
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.

[libcpu][C28x] Fix bugs of old c28x interrupt api which can not save and restore int status 
In C28x DSP, interrupt status are stored in ST1 register. Both INTM and DBGM is used for masking interrupt, while the latter one is used in real-time debug mode. The origin function rudely enable and disable the interrupt without considering the recent interrupt status, which not only may cause  problem in some situation but also is not in conformity with rt-thread design specifications. The new api will fix this bug.

Files that rely on this file should include 'board.h' instead.
