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.
