Currently, we check cpuidle_ops.suspend every time when entering a
low-power idle state. But this check could be avoided in this hot path
by moving it into arm_cpuidle_read_ops() to reduce arm_cpuidle_suspend
overhead a bit.

I'm not sure the upstream merging path this patch should follow, Per my
understanding, I need to put it into Russell's PATCH system.  

Or alternatively through arm-soc

Got it. thanks.
