Shared PCIe bus range tracking.
An AssignedBusRange holds the segment-local bus range
(secondary_bus, subordinate_bus) assigned to the PCIe port that owns a
device. It is updated automatically by
ConfigSpaceType1Emulator
when the guest writes bus number registers, and on restore/reset.
Consumers (ITS wrappers, SMMU) read the bus range to compose a segment-local device identity (BDF) from the assigned bus numbers.
