depthcharge: correct SD controller base clock frequency

Added clock_base which saves base clock frequency read out from
CAP register. So frequency divider can be calculated correctly.
This also fixes min and max SD clock settings for their intended
purpose.

BUG=chrome-os-partner:42065
BRANCH=None
TEST=Built and booted glados from SD card.
