[PATCH 1/3] mfd: cros_ec: Add activity motion sense definitions

[Thierry Escande]

From: Gwendal Grignou <gwen...@chromium.org>

This adds motion sense definitions to the commands header related to the
activity sensors attached behind the ChromeOS Embedded Controller.
Supported activities are MOTION and DOUBLE_TAP.
