usb: typec: tcpci: add vconn over current fault handling to maxim_core
Add TCPC_FAULT_STATUS_VCONN_OC constant and corresponding mask definition. Maxim TCPC is capable of detecting VConn over current faults, so add fault to alert mask. When a Vconn over current fault is triggered, put the port in an error recovery state via tcpm_port_error_recovery.
