[PATCH 3/4] soc-camera: add new bus width and signal polarity flags

[Guennadi Liakhovetski <g.liakhovetski@xxxxxx>]

In preparation for i.MX31 camera host driver add flags for 4 and 15 bit bus
widths and for data lines polarity inversion.

Signed-off-by: Guennadi Liakhovetski <lg@xxxxxxx>

Careful, soc_camera_bus_param_compatible() is more selective with this 
patch, some configurations might break.
