msm: hotplug: Remove most suspend operations

Thanks to changes in the sound subsystem, cpu usage while listening to
audio streams in now greatly reduced (if supported by the audio HAL).

Before, the cpu was under severe load about half of the time. Now we're
idling along at minimum frequency. There is no need for most suspend
operations any more. We are now just shortly onlining all cpus to speed
up display resume operations.
