The driver dug the supported link frequency up from the V4L2 fwnode
endpoint and used it internally, but failed to report this in the
LINK_FREQ and PIXEL_RATE controls. Fix this.

Fixes: 0677a2d9b735 ("media: ov2740: Add support for 180 MHz link frequency")
Cc: stable@vger.kernel.org # for v6.8 and later
