Badhri Jagan Sridharan a87cc08c31 Revert "usb: typec: tcpm: fix cc role at port reset"
commit b717dfbf73 upstream.

This reverts commit 1e35f07439.

Given that ERROR_RECOVERY calls into PORT_RESET for Hi-Zing
the CC pins, setting CC pins to default state during PORT_RESET
breaks error recovery.

4.5.2.2.2.1 ErrorRecovery State Requirements
The port shall not drive VBUS or VCONN, and shall present a
high-impedance to ground (above zOPEN) on its CC1 and CC2 pins.

Hi-Zing the CC pins is the inteded behavior for PORT_RESET.
CC pins are set to default state after tErrorRecovery in
PORT_RESET_WAIT_OFF.

4.5.2.2.2.2 Exiting From ErrorRecovery State
A Sink shall transition to Unattached.SNK after tErrorRecovery.
A Source shall transition to Unattached.SRC after tErrorRecovery.
