rambi: Make eMMC CLK pull-down and change pull strengths to 20K

Hardware / Coreboot - Shawn Nematbakhsh [chromium.org] - 12 May 2014 15:11 UTC

eMMC CLK was incorrectly configured as PULL_UP, but should have been PULL_DOWN. 2K pulls somehow masked this problem.

BUG=chrome-os-partner:24353 TEST=Verify eMMC is bootable on Rambi on boards that previously failed with an all-20K, all-PU eMMC pin configuration. BRANCH=None
