camera_sensor: Add minimum and maximum line length to IPACameraSensorInfo
Add fields for minimum and maximum line length (in units of pixels) to
the IPACameraSensorInfo structure. This replaces the existing lineLength
field.
Update the ipu3, raspberrypi and rkisp1 IPAs to use
IPACameraSensorInfo::minLineLength instead of
IPACameraSensorInfo::lineLength, as logically we will always want to use
the fastest sensor readout by default.
Since the IPAs now use minLineLength for their calculations, set the
starting value of the V4L2_CID_HBLANK control to its minimum in
CameraSensor::init().
