When servo_v4 acts as a debug test system (DTS) its expected use
case is for triggering CCD mode and Faft testing. To that end, its
desired default data role is to be a UFP so that the enet and USB
port are accessible by the DUT. However, when servo is acting a
regular SRC port, it makes more sense for the data role pairing to
be consistent with a normal SRC port device which is SRC/DFP.
BUG=b:64720447
BRANCH=servo
TEST=Tested with Eve using twinkie USB PD analyzer. Verified that when
DTS mode is enabled a data role swap request is sent to the DUT and
when DTS mode is disabled that servo_v4 does not send a data role swap
request.
