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
