commit 7f9f5f80c9dc5de2ebfdfa9927d19f1454b47785

google/snow: Change MMC0 to work in 8 bit mode.

The MMC0 on google/snow can run in 8 bit mode. To simplify driver development,
    we explicitly disabled it (using zero, which runs in 1-bit / 4-bit mode) before.
    The 8 bit mode is ready now.

Verified to boot on google/snow, and got MMC0 working.
