The driver relies on the compatible string from DT to determine which FW configuration file it should load. The DTS spec allows for '/' as part of the compatible string. We change this to '-' so that we will still be able to load the config file, even when the compatible has a '/'. This fixes explicitly the firmware loading for "solidrun,cubox-i/q".
