x86/PCI: ACPI based PCI gap calculation
Using ACPI to find free address space allows us to find a gap for the
unallocated PCI resources or MMIO resources for hotplug devices within
the BIOS allowed PCI regions.
It works by evaluating the _CRS object under PCI0 looking for producer
resources. Then searches the e820 memory space for a gap within these
producer resources.
