    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 thought disabling it (using zero, which runs in 1-bit / 4-bit mode) may help.
    However, after some experiments in payload drivers, setting pinmux to 8 bit mode
    can still allow MMC to run in 1-bit / 4-bit mode, so it's pretty safe to enable
    8 bit mode by default for better performance.
    Verified to boot on google/snow, and got MMC0 working.
