mainboard/google/reef: Configure sd card pins 

Since the sd card cmd, data, cd lines are configured
as native mode, allow the native controller to control
the termination.
Configure SDCARD_CLK_FB which is used for calibrating the
timing of the actual clock buffer.

BUG==chrome-os-partner:53747
TEST=verify sd card detection
