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.

This patch adds support for uprobes on csky architecture.
Just like kprobe, it support single-step and simulate instructions.
