rambi: limit SD card controller to 2.0 spec

The rambi board can only meet the SD card 2.0 specification.
    Therefore, the controller capabilities need to be overridden
    to match.

BUG=chrome-os-partner:24423
    BRANCH=None
    TEST=Built and booted. /sys/kernel/debug/mmc0/ios shows
         high speed as maximum timing as well as 3.3V signal voltage.
