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.
