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.
