Badhri Jagan Sridharan 901789745a usb: typec: 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.

echo source > /sys/class/typec/port0/port_type

Before:
[  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

After:

[  151.072440] CC1: 3 -> 0, CC2: 0 -> 0 [state PORT_RESET, polarity 0, disconnected]
[  151.172117] state change PORT_RESET -> PORT_RESET_WAIT_OFF [delayed 100 ms]
[  151.172136] pending state change PORT_RESET_WAIT_OFF -> SRC_UNATTACHED @ 870 ms [rev3 NONE_AMS]
