PM / core: Split dpm_suspend_noirq() and dpm_resume_noirq()
Put the device interrupts disabling and enabling as well as cpuidle_pause() and cpuidle_resume() called during the "noirq" stages of system suspend into separate functions to allow the core suspend-to-idle code to be optimized (later). The only functional difference this makes is that debug facilities and diagnostic tools will not include the above operations into the "noirq" device suspend/resume duration measurements.
