Both upstream and the 4 duplicated drivers have similar functionality. Also,
the upstream driver is actively maintained. So, there's no sense on accepting
those duplicated drivers.

Also, just replacing one existing driver by a newer one will cause regressions
on some already fixed bugs and remove some improvements that the upstream driver
suffered.

If there's a bug or a lack of functionality on em28xx, cx25843, xc5000 or
tuner-xc2028, it is just a matter of submitting patches fixing those bugs or
adding newer features.
