    x86: add kernel module for sp5100_tco watchdog
    
    This change adds the sp5100_tco driver as a kernel module for the x86
    target. Specifically, this can be used by the PCEngines APU2/APU3. The
    reason for having this as a kernel module is to allow users to
    load/unload it on demand, as the I2C interface on the APU2/APU3 will not
    work while this module is loaded. More info can be found on GitHub at
    https://github.com/riptidewave93/LEDE-APU2/pull/5#issuecomment-255667736
