Subject: [PATCH 2/2] Export deferrable timer through workqueue and use it in ondemand governor



Add a new deferrable delayed work init. This can be used to schedule work
that are 'unimportant' when CPU is idle and can be called later, when CPU
eventually comes out of idle.

Use this init in cpufreq ondemand governor.
