[PATCH 04/15] net: sun8i_emac: Remove pointless wrapper functions

[Andre Przywara]

Apparently due to copying from some older or converted driver, the
sun8i_emac driver contains pointless wrapper functions to bridge
between a legacy driver and the driver model.

Since sun8i_emac is (and always was) driver model only, there is no
reason to have those confusing wrappers. Just remove them, and use
the driver model prototypes directly.
