iio: add driver for Freescale MMA9553

Add support for Freescale MMA9553L Intelligent Pedometer Platform.

The following functionalities are supported:
- step counter (counts the number of steps using a HW register)
- step detector (generates an iio event at every step the user takes)
- activity recognition (rest, walking, jogging, running)
- speed
- calories
- distance

To get accurate pedometer results, the user's height, weight and gender
need to be configured.

The specifications can be downloaded from:

iio: accel: mma9551: split driver to expose mma955x api

Freescale has the MMA955xL family of devices that use the
same communication protocol (based on i2c messages):
http://www.freescale.com/files/sensors/doc/data_sheet/MMA955xL.pdf.

To support more devices from this family, we need to split the
mma9551 driver so we can export the common functions that will
be used by other mma955x drivers.
