iio: mma8452: add support for MMA8453Q accelerometer chip
This adds support for the 10 bit version if Freescale's accelerometers
of this series. The datasheet is available at Freescale's website:
http://cache.freescale.com/files/sensors/doc/data_sheet/MMA8453Q.pdf
It creates a devicetree bindings file to document the new functionality
and removes the driver from the trivial-devices list.
