New version of this patch.
Should I split it up into two, one for the change to input.h and one for the change in via-pmu?
Ben, what about recognising the PMU here? What else can it report/what else should I pick up? What about older versions?
---
This patch adds an input device for the button and lid switch so that userspace gets notified about the user pressing them via the standard input layer.
