[PATCH 5/9] libcamera: v4l2_subdevice: Drop V4L2SubdeviceFormat::bitsPerPixel()

[Laurent Pinchart]

The V4L2SubdeviceFormat::bitsPerPixel() function is just a wrapper
around a MediaBusFormatInfo lookup. It made sense when the
MediaBusFormatInfo class was not exposed outside of the compilation
unit, but is now redundant. Drop it and use MediaBusFormatInfo in the
only caller.
