csky: Fixup add zero_fp fixup perf backtrace panic2019-09-30T02:26:32ZGuo Renren_guo@c-sky.com2019-09-25T11:56:16Zurn:sha1:48ede51fd94fe9251058fc85626b2aeb5cbb5884
We need set fp zero to let backtrace know the end. The patch fixup perf
callchain panic problem, because backtrace didn't know what is the end

The gcc option "-mbacktrace" will push fp(r8),lr into stack and we could
unwind the stack with:
fp = *fp
lr = (unsigned int *)fp[1]
