This change adds a delayed_work to detect the release of onkey since HW will
not generate interrupt for it.
At the same time, we move the KEY event to POWER instead of SUSPEND, which
will be suitable for both Android and Linux. Userspace PowerManager Daemon
will decide to suspend or shutdown based on how long we have touched onkey.

New version of the PCU firmware supports two new commands:
- IMS_PCU_CMD_OFN_SET_CONFIG which allows to write data to the
registers of one finger navigation(OFN) chip present on the device
- IMS_PCU_CMD_OFN_GET_CONFIG which allows to read data form the
registers of said chip.
This commit adds two helper functions to use those commands and sysfs
attributes to use them. It also exposes some OFN configuration
parameters via sysfs.

uinput is used in the xorg-integration-tests suite and in the wayland
test suite. These automated tests suites create many virtual input
devices and then hook something to read these newly created devices.
Currently, uinput does not provide the created input device, which means
that we rely on an heuristic to guess which input node was created.
The problem is that is heuristic is subjected to races between different
uinput devices or even with physical devices. Having a way to retrieve
the sysfs path allows us to find without any doubts the event node.
