[PATCH 1/6] domain: Add PCI configuration feature infrastructure
Add basic infrastructure for PCI configuration feature including:
- New PCI configuration structure in domain_conf.h
- Add VIR_DOMAIN_FEATURE_PCI enum and string conversion
- Add pci field to virDomainDef to store PCI configuration
This will be used to support QEMU's highmem-mmio-size machine property
for the aarch64 virt machine type.
