intel/fsp_broadwell_de: Do not use hard coded SCI IRQ for ACPI

The SCI interrupt can be routed to different IRQs using ACPI control
    register. Instead of using hard coded IRQ9 for ACPI table generation
    read back the register and return the used IRQ number. This way SCI IRQ
    can be modified (e.g. for a given mainboard) and ACPI tables will
    remain consistent.
