csky: Fixup perf probe -x hungup
case:
# perf probe -x /lib/libc-2.28.9000.so memcpy
# perf record -e probe_libc:memcpy -aR sleep 1
System hangup and cpu get in trap_c loop, because our hardware
singlestep state could still get interrupt signal. When we get in
uprobe_xol singlestep slot, we should disable irq in pt_regs->psr.
And is_swbp_insn() need a csky arch implementation with a low 16bit
mask.
