PIRQ routing is pretty much common in Intel chipset. It has several PIRQ links (normally 8) and corresponding registers (either in PCI configuration space or memory-mapped IBASE) to configure the legacy 8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing support using device tree and move it to a common place, so that we can easily add PIRQ routing support on a new platform.

Changes in v2:
- Include dt-bindings/interrupt-router/intel-irq.h to avoid duplication
- Remove board_fill_irq_info() since all routing information is defined in dts
