Jisheng Zhang c3fbbf9308 ARM: 8586/1: cpuidle: make arm_cpuidle_suspend() a bit more efficient
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.
