[PATCH 4/4] Documentation: DT: lis302: update wakeup binding

[Sebastian Reichel <sre-8fiUuRrzOP0dnm+yROfE0A@public.gmane.org>]

This updated the documentation of the DT binding to
describe the added wakeup threshold and second wakeup
engine.

It also adds a note, that the axis values may be
negative.
