2023-01-08include/hw/pci: Include hw/pci/pci.h where neededMarkus Armbruster
hw/pci/pcie_sriov.h needs PCI_NUM_REGIONS. Without the previous commit, this would close an inclusion loop: hw/pci/pci.h used to include hw/pci/pcie.h for PCIExpressDevice, which includes pcie_sriov.h for PCIESriovPF, which now includes hw/pci/pci.h for PCI_NUM_REGIONS.
