[RFC PATCH 2/8] iio: core: Introduce IIO_ACTIVITY channel

[Daniel Baluta <daniel.baluta@intel.com>]

This channel will be used for exposing information about
some activity composite sensors including:
	* motion (running, jogging, walking, still).
	* step counter
	* step detector

This will offer an interface for Android composite sensors
defined here:
http://source.android.com/devices/sensors/composite_sensors.html

This sensors are supported by Freescale's MMA9553 device.
