[PATCHv2 5/8] iio: mma8452: add devicetree binding document

[Martin Kepplinger <martink@posteo.de>]

As we support more chips now, add a binding document and remove it from
i2c trivial-devices.txt list.

The binding document is further extended in a later patch of this series.

builds a nice list of supported compatible strings.

thanks!

+    * "fsl,mma8652"
+    * "fsl,mma8453"
