ivtv: simplify gpio initialization for XCeive tuners.
From: Hans Verkuil <hverkuil@xs4all.nl>
Separate gpio_init field and xceive_pin and combine the two when
the gpio is initialized. So there is no longer any need to set the
xceive pin in the gpio_init values, simplifying the creation of a
new card definition.
