@param[in] AllocAttributes Allocation attributes.
@param[in] RootBusNumber The bus number to store in RootBus.
@param[in] DmaAbove4G DMA above 4GB memory.
@param[in] MaxSubBusNumber The inclusive maximum bus number that can be
assigned to any subordinate bus found behind any
PCI bridge hanging off this root bus.
@param[in] NoExtendedConfigSpace No Extended Config Space.
The caller is repsonsible for ensuring that
RootBusNumber <= MaxSubBusNumber. If
RootBusNumber equals MaxSubBusNumber, then the
root bus has no room for subordinate buses.
