msm:rq_stats: Add hotplug disable attribute
Register for suspend and resume notifications from kernel. This should
be done as part of core_initcall so as to receive notification as close
as possible to the actual event. Add hotplug_disable attribute to
rq-stats node. Set/clear this attribute based on the suspend/resume events.
