csky: Fixup ftrace modify panic

Browse source

[ Upstream commit 359ae00d12 ]

During ftrace init, linux will replace all function prologues
(call_mcout) with nops, but it need flush_dcache and
invalidate_icache to make it work. So flush_cache functions
couldn't be nested called by ftrace framework.
