tcpc: add support for TCPC with integrated high-speed muxes
The TCPCI specification defines ane optional register
18h 'CONFIG_STANDARD_OUTPUT' providing a standardized way
of steering the high-speed muxes.
Implement the feature as a usb_mux_driver, under the conditional flag
CONFIG_USB_PD_TCPM_MUX.
The USB PD port index should be set in the port_addr field of the
'usb_mux' structure.
