Subject: [PATCH] usb: typec: tcpm: handle SRC_STARTUP state if cc changes

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.
