    fsp_baytrail: Change A, A, A, A IRQ routing to A, A, A, B
    
    Devices that have their interrupt routing set to A, A, A, A don't get
    any interrupt values assigned because that series evaluates to 0.  The
    code that sets the interrupt values checks to make sure a value is set
    by verifying that it's not 0.  On Bay Trail, these are all
    single-function graphics devices, so by changing one of the unused
    interrupt lines from A to any other value, it assigns the values
    correctly.
    
    This issue did not affect ACPI interrupt routing.
    
    This is just a workaround, and the root issue still needs to be fixed.
