V4L/DVB (13828): uvcvideo: Make the quirks module parameter override the built-in quirks
The quirks module parameter is or'ed with the built-in quirks for the
device being probed. This make it impossible to disable a built-in quirk
without recompiling the driver.
Replace the built-in quirks with the quirks module parameter instead of
or'ing the values.
