Add support for runtime power management so that the device is
turned off when not used (when the userspace holds no open
handles of the input device). The device uses autosuspend with a
default delay of 2 seconds, so the device will suspend if no
handles to it are open for 2 seconds.

The runtime management support is only available if the gpio pins
are properly initialized from ACPI/DT.
