acpi/crs: Prevent bad ranges for host bridges

Prevent _CRS resources being quietly chopped off and instead throw an
assertion. _CRS is used by host bridges to declare regions of io and/or
memory that they consume. On some (all?) platforms the host bridge
doesn't have PCI header space and so they need some way to convey the
information.
