kukui: Enable DP.
On plug DP dongle, we sohuld:
1. set USB_C0_DP_POLARITY bit accordingly
2. set USB_C0_DP_OE_L low
3. set USB_C0_HPD_OD high
On unplug DP dongle, we should:
1. set USB_C0_DP_OE_L high
2. set USB_C0_HPD_OD low
TEST=pd 0 dualrole on; plug DP dongle, see GPIO pins set accordingly.
TEST=unplug DP dongle, see GPIO pins set accordingly.
TEST=plug dp and seeing output to external display for both polarity.
BUG=b:114162810
