    cxgb4: Add support for T4 configuration file

    This patch adds patch series from linux-next tree to add support for T4
    configuration file.

    Starting with T4 firmware version 1.3.11.0 the firmware now supports device
    configuration via a Firmware Configuration File. The Firmware Configuration
    File was primarily developed in order to centralize all of the configuration,
    resource allocation, etc. for Unified Wire operation where multiple
    Physical / Virtual Function Drivers would be using a T4 adapter simultaneously.

    The Firmware Configuration file can live in three locations as shown below
    in order of precedence.
    1) User defined configuration file: /lib/firmware/cxgb4/t4-config.txt
    2) Factory Default configuration file written to FLASH within
       the manufacturing process.
    3) Hardwired driver configuration.
