These accelerometers have bindings used in the kernel and
several device trees but no proper bindings documentation.
Add it.
Also add a compatible for the BMA222 that I am right now
adding support for in the driver.

ChangeLog v2->v3:
- Fix up an include directive in the example to be
outside of the I2C node.
ChangeLog v1->v2:
- Rename to simply bosch,bma255.yaml after one of the
common accelerometers.
- Specify that the SPI uses a 4-wire interface.
- Specify maximum SPI clock frequency to 10MHz. (Checked
all the datasheets.)
