[media] adv7604/adv7842: fix il_vbackporch typo and zero the struct
Both adv7604 and adv7842 had the same typo in the code that sets
the vertical backporch for the second interlaced field: it was
assigned to vbackporch instead of il_vbackporch.
In addition, the timings struct wasn't zeroed in the adv7842 driver,
leaving several fields to undefined values causing the timing match
function to fail.
