[PATCH 1/4] Input: Add trackpoint doubletap and system debug info keycodes

[Mark Pearson <mpearson-lenovo@squebb.ca>]

Add support for new input events on Lenovo laptops that need exporting to
user space.

Lenovo trackpoints are adding the ability to generate a doubletap event.
Add a new keycode to allow this to be used by userspace.

Lenovo support is using FN+N with Windows to collect needed details for
support cases. Add a keycode so that we'll be able to provide similar
support on Linux.
