baytrail: there is a chance that USBPHY_COMPBG is set to 0 

Due to some projects don't have the correct settings in devicetree.cb
so put this change in case those projects without are setting in devicetree.cb

BUG=chrome-os-partner:30690
BRANCH=none
TEST=emerge-rambi coreboot without problem
     checked the USBPHY_COMPBG is configured properly
     even there is no setting in devicetree
