[media] v4l2: replace try_mbus_fmt by set_fmt

The try_mbus_fmt video op is a duplicate of the pad op. Replace all uses
in sub-devices by the set_fmt() pad op.

Since try_mbus_fmt and s_mbus_fmt both map to the set_fmt pad op (but
with a different 'which' argument), this patch will replace both
try_mbus_fmt and s_mbus_fmt by set_fmt.
