usb: typec: tcpm: fix cc role at port reset

[Frank Wang]

In the current implementation, the tcpm set CC1/CC2 role to open when
it do port reset would cause the VBUS removed by the Type-C partner.

This sets CC1/CC2 according to the default state of port to fix it.

Comments are suggested by Guenter Roeck.
