pci: Ignore PCRx devices resources

[andrew]

Summary

Some systems provide two PCI root complex devices in the ACPI tables.
Allow us to skip known pci-like devices even if they aren't detected
as a PCI root complex.

Works for me!

Note that this case is for x86 truly is for PCI bridges only. If this device isn't a PCI bridge, I think I'd rather just have a separate quirk, so something like:

/* existing comment and code for PCI-bridges */

/*
  * Ignore memory resources for devices known to list invalid resources.
  */
if (type == SYS_RES_MEMORY && ACPI_ID_PROBE(...) <= 0)
    return (true);

I would also just rename pcilike_ids to bad_memresource_ids or some such in this case.

Is the device in question duplicating the full memory decoded ranges of the PCI bridge, or is it just listing resource that are a subset but conflict with the bridge? (It might be nice to see the resource ranges used by the device in question and the PCI bridge)
