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

From: Gwendal Grignou <gwendal@...omium.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.
