tcpm: Ignore CC and vbus changes in PORT_RESET change

After PORT_RESET, the port is set to the appropriate
default_state. Ignore processing CC changes here as this
could cause the port to be switched into sink states
by default.

[  154.528547] pending state change PORT_RESET -> PORT_RESET_WAIT_OFF @ 100 ms
[  154.528560] CC1: 0 -> 0, CC2: 3 -> 0 [state PORT_RESET, polarity 0, disconnected]
[  154.528564] state change PORT_RESET -> SNK_UNATTACHED
