    rambi: configure SD card signals
    
    Rambi 1.5 boards use the native SD card controller on baytrail.
    Therefore, enable those signals. The CLK, D*, and CMD pins use
    2K pulls as these were shown to not exhibit any errors when
    doing reads or writes to a DDR50 sd card.
    
    Note that if a servo is connected on needs to enable the
    sd_vref_sel rail to pp1800 as this causes issues with card
    detect if it is not set to pp1800.
    
    BUG=chrome-os-partner:24312
    BRANCH=None
    TEST=Built and booted. Tested sd card read and write works in kernel.
         Also noted that write protect detection works as well.
