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.
