    ionic: add module eeprom channel data to ionic_if and ethtool

    Make the CMIS module type's page 17 channel data available for
    ethtool to request.  As done previously, carve space for this
    data from the port_info reserved space.

    In the future, if additional pages are needed, a new firmware
    AdminQ command will be added for accessing random pages.
