[PATCH v3 03/12] dt-bindings: media: i2c: max9286: Add property to select bus width

The GMSL serial data bus width is normally selected by the BWS pin, but
it can also be configured by software. Add a DT property that allows
overriding the value of the BWS-selected bus width to support systems
whose BWS pin doesn't result in the correct value.
