OvmfPkg: clone PciHostBridgeDxe from PcAtChipsetPkg The source code is copied verbatim, with the following two exceptions: - the UNI files are dropped, together with the corresponding UNI references in the INF file, - the INF file receives a new FILE_GUID. The OVMF DSC and FDF files are at once flipped to the cloned driver.
