sb/intel/lynxpoint: Automatically generate the ACPI PCI routing table

This patch is based on a8a9f34e9b7b ("sb/intel/i82801{g,j}x:
Automatically generate ACPI PIRQ tables")

Tested on an ASRock H81M-HDS. The generated _PRT object looks correct,
and the system doesn't show any issue when running. The following
assignments occur:

	ACPI_PIRQ_GEN: PCI: 00:02.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:03.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:14.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:16.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:1a.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:1b.0: pin=0 pirq=6
	ACPI_PIRQ_GEN: PCI: 00:1c.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:1c.1: pin=1 pirq=1
	ACPI_PIRQ_GEN: PCI: 00:1c.2: pin=2 pirq=2
	ACPI_PIRQ_GEN: PCI: 00:1c.3: pin=3 pirq=3
	ACPI_PIRQ_GEN: PCI: 00:1d.0: pin=0 pirq=7
	ACPI_PIRQ_GEN: PCI: 00:1f.2: pin=1 pirq=3
	ACPI_PIRQ_GEN: PCI: 00:1f.3: pin=2 pirq=2

Also tested on a Google Peppy board. The following assignments occur:

	ACPI_PIRQ_GEN: PCI: 00:02.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:03.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:14.0: pin=0 pirq=2
	ACPI_PIRQ_GEN: PCI: 00:1b.0: pin=0 pirq=6
	ACPI_PIRQ_GEN: PCI: 00:1c.0: pin=0 pirq=0
	ACPI_PIRQ_GEN: PCI: 00:1d.0: pin=0 pirq=3
	ACPI_PIRQ_GEN: PCI: 00:1f.2: pin=0 pirq=6
	ACPI_PIRQ_GEN: PCI: 00:1f.3: pin=1 pirq=2
	ACPI_PIRQ_GEN: PCI: 00:1f.6: pin=2 pirq=1

A diff of the _PRT object for the Google Peppy board is below. The code
used in the diff has been modified for clarity, but the semantics remain
the same. To summarise the diff:

* The disabled PCIe root ports are no longer included.

* The LPC controller is no longer included, as it has no interrupt pin.
  The pins for the remaining LPC devices are each one less. Perhaps the
  original _PRT object was incorrect?

* The SDIO device is no longer included, as it is disabled.

* The Serial IO devices are no longer included, but that is due to a
  separate issue I am having with this system (the devices don't show up
  under Linux regardless of this patch). In short: their omission is not
  a fault of this patch.
