PM: runtime: Extend support for wakeirq for force_suspend|resume

Browse source 
A driver that makes use of pm_runtime_force_suspend|resume() to support
system suspend/resume, currently needs to manage the wakeirq support
itself. To avoid the boilerplate code in the driver's system suspend/resume
callbacks in particular, let's extend pm_runtime_force_suspend|resume() to
deal with the wakeirq.
