intel/fsp_baytrail: Add PCI Root Port IRQ Routing

This change generates the ASL tables needed for the PCIe bridge routing.

It generates this ASL (swizzled for each of the 8 functions)
Name(RP1P, Package()
{
	Package() {0x0000ffff, 0, \_SB.PCI0.LPCB.LNKE, 0 },
	Package() {0x0000ffff, 1, \_SB.PCI0.LPCB.LNKF, 0 },
	Package() {0x0000ffff, 2, \_SB.PCI0.LPCB.LNKG, 0 },
	Package() {0x0000ffff, 3, \_SB.PCI0.LPCB.LNKH, 0 },
})
Name(RP1A, Package()
{
	Package() {0x0000ffff, 0, 0, 20 },
	Package() {0x0000ffff, 1, 0, 21 },
	Package() {0x0000ffff, 2, 0, 22 },
	Package() {0x0000ffff, 3, 0, 23 },
})
Device(RP01) {
	Name(_ADR, 0x1c0001)
	Name(_PRW, Package() {
		0, 0
	})
	Method(_PRT,0) {
		If(PICM) {
			Return (RP1A)
		} Else {
			Return (RP1P)
		}
	}
