Zhenzhong Duan d4157195bd smmu: Clear SMMUPciBus pointer cache when system reset
s->smmu_pcibus_by_bus_num is a SMMUPciBus pointer cache indexed
by bus number, bus number may not always be a fixed value,
i.e., guest reboot to different kernel which set bus number with
different algorithm.

This could lead to smmu_iommu_mr() providing the wrong iommu MR.
