Just like kprobe, it support single-step and simulate instructions.

csky: Add kprobes supported2020-04-03T03:14:17ZGuo Renguoren@linux.alibaba.com2020-04-01T01:17:02Zurn:sha1:33e53ae1ce413a081254e686d9b27cc1b3585e2f
This patch enable kprobes, kretprobes, ftrace interface. It utilized
software breakpoint and single step debug exceptions, instructions
simulation on csky.
We use USR_BKPT replace origin instruction, and the kprobe handler
prepares an excutable memory slot for out-of-line execution with a
copy of the original instruction being probed. Most of instructions
could be executed by single-step, but some instructions need origin
pc value to execute and we need software simulate these instructions.
