>
> Expose SMA and U.FL connectors as ptp_pins on E810-T based adapters and allow controlling them.
>
> E810-T adapters are equipped with:
> - 2 external bidirectional SMA connectors
> - 1 internal TX U.FL
> - 1 internal RX U.FL
>
> U.FL connectors share signal lines with the SMA connectors. The TX U.FL1 share the line with the SMA1 and the RX U.FL2 share line with the SMA2.
> This dependence is controlled by the ice_verify_pin_e810t.
>
> Additionally add support for the E810-T-based  devices which don't use the SMA/U.FL controller. If the IO expander is not detected don't expose pins and use 2 predefined 1PPS input and output pins.
