[media] mxl5005s: fix compiler warning
Removed the unused Xtal_Int variable. That made it also possible to remove a related function. However, the code of that function has been preserved in a comment describing an equation. Without that function that comment would have been hard to understand. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
