libcamera: formats: Add YUV444 and YVU444 pixel formats
Extend planar YUV format support with 4:4:4 formats. Those formats are used by the i.MX8 ISI driver that will be supported by the simple pipeline handler. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
