zephyr: tcpc: Add support for multiple alternatives per port
Add support for multiple TCPC alternatives on each USB-C port
TCPC chips that are candidates for runtime selection must add the
"is-alt" property to the TCPC definition.
The board specific code then calls TCPC_ENABLE_ALTERNATE_BY_NODELABEL,
specifying both the USB-C port to update, and the nodelabel of the new
TCPC device.
