exynos/snow: get rid of board-specific arbitration code

Snow's AP, EC, PMU, and smarty battery share a bus. Both the AP and
    EC can act as a master, so to avoid conflicts an arbitration
    mechanism consisting of two GPIOs is used.

By default, the AP "owns" the bus unless it is off (in which case
    the EC doesn't monitor the arbitration pins). This means the boot
    firmware does not need to worry about these lines. The payload may
    if it needs to communicate with the EC, though.

In any case, board-specific bus arbitration logic does not belong
    in a low-level driver that is supposed to be generic for an entire
    CPU family. If the payload needs to talk to the EC, we'll deal with
    it there.
