The previous change to make ov9281 always run in continuous clock mode causes problems on Pi3 for reasons that aren't fully understood. Pi4 is quite happy with it. Change the default back to being non-continuous clock, and add an override to select continuous clock mode and its slightly greater max frame rate. https://forums.raspberrypi.com/viewtopic.php?p=2300215 Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
