Subject: [PATCH] usb: typec: tcpm: clear pd_event queue in PORT_RESET

When a Fast Role Swap control message attempt results in a transition to ERROR_RECOVERY, the TCPC can still queue a TCPM_SOURCING_VBUS event.

If the event is queued but processed after the tcpm_reset_port() call in the PORT_RESET state, then the following occurs:
1. tcpm_reset_port() calls tcpm_init_vbus() to reset the vbus sourcing and sinking state
2. tcpm_pd_event_handler() turns VBUS on before the port is in the default state.
3. The port resolves as a sink. In the SNK_DISCOVERY state, tcpm_set_charge() cannot set vbus to charge.

Clear pd events within PORT_RESET to get rid of non-applicable events.
