Xu Yang 1d4e9f27d2 usb: typec: tcpm: handle SRC_STARTUP state if cc changes
commit 6d91017a295e9790eec02c4e43f020cdb55f5d98 upstream.

TCPM for DRP should do the same action as SRC_ATTACHED when cc changes in
SRC_STARTUP state. Otherwise, TCPM will transition to SRC_UNATTACHED state
which is not satisfied with the Type-C spec.

Per Type-C spec:
DRP port should move to Unattached.SNK instead of Unattached.SRC if sink
removed.
