veyron: fievel/tiger: congiure usb and hdmi

Browse source 
Enable 5v_drv for usb and hdmi.

For tiger(chromebase with eDP), set the vop mode to
VOP_MODE_AUTO_DECTECT so it would fall through
to hdmi if there is not edp(or edp initialized failed).
For fievel(chromebox without eDP), set vop mode to VOP_MODE_HDMI.

BRANCH=veyron
BUG=none
TEST=check usb/hdmi function
