Eve: Enable usb device modefactory-poppy-10509.B
For the dual data role, when the state is UFP
assert the otg pins to activate the usb device controller.
This will enable usb gadget mode and the board will act as
usb device instead of host.
For DFP state, de-assert the otg pins to activate the host mode.
BUG=b:74339386
BRANCH=NONE
TEST=Connect two Eve boards with the usb type c cable.
On ec console, type the command usb pd 0 swap data.
pd 0 state should return UFP mode.
Verify that the otg pins are high (USB2_OTG_ID and USB2_OTG_VBUSSENSE).
