servo_v4: Support sink roles with PD comm enabled
For the normal lab use, emulating a sink has no PD comm, like a passive
hub. For the PD FAFT use, we need to validate some PD behavior, should
support sink roles with PD comm enabled. Two new roles "pdsnk" and
"pdsnkdts" are introduced.
BRANCH=servo
BUG=b:134700685
TEST=Typed "cc pdsnk" or "cc pdsnkdts" can transit the DUT port to
the PD state "SNK_READY", instead "SNK_DISCOVERY".
