- Support Prefetchable Memory.
- Use the correct rman when allocating memory and ioports.
- Translate PCI addresses in bus_alloc_resource to allow physical
addresses that are different than pci addresses.

Both ACPI and FDT support bus ranges for pci host bridges. Update
pci_host_generic*.[ch] with a default implementation to support this.
This will be used in the next set of changes for ACPI based host
bridge. No functional changes in this commit.

FDT attachment to a new file. A separate ACPI attachment will then be added
to allow arm64 servers with ACPI to use it over FDT.
This should also help with merging this with the ofwpci driver, with
further work needed to remove restrictions this driver places on resource
allocation.

translate the pci rid to a controller ID. The translation could be based
on the 'msi-map' OFW property, a similar ACPI option, or hard-coded for
hardware lacking the above options.

interface. The pcib driver will need to perform a device specific lookup
to find the MSI controller and pass this to intrng as the xref. Intrng
will finally find the controller and have it handle the requested operation.

If Enhanced Allocation is not used, we can't allocate any random
range. All internal devices have hardcoded place where they can
be located within PCI address space. Fortunately, we can read
this value from BAR.
