Guo Ren b6a41435c8 csky: syscache: Fixup duplicate cache flush
[ Upstream commit 6ea42c84f3 ]

The current csky logic of sys_cacheflush is wrong, it'll cause
icache flush call dcache flush again. Now fixup it with a
conditional "break & fallthrough".

Fixes: 997153b9a7 ("csky: Add flush_icache_mm to defer flush icache all")
Fixes: 0679d29d3e ("csky: fix syscache.c fallthrough warning")
