[PATCH v3 1/2] dt-bindings: iio: bmc150_magn: Document and fix missing compatibles

[Krzysztof Kozlowski]

The driver supports also BMC156B and BMM150B.  Add existing compatibles
marking the BMM150B one as deprecated (due to redundant suffix "_magn"
because the device unlike two others is a magnetometer only).  Introduce
a new, proper compatible for the deprecated one.

Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

Changes since v2:
1. Add compatible only for bmm150.

Changes since v1:
1. Mark old compatibles as deprecated, add new one.
