OvmfPkg/PciHostBridgeLibScan: remove QEMU (fw_cfg) support
The "OvmfPkg/Library/PciHostBridgeLibScan/PciHostBridgeLibScan.inf" instance is used in the following platforms in edk2: OvmfPkg/Bhyve/BhyveX64.dsc OvmfPkg/OvmfXen.dsc Both platforms define "PcdPciDisableBusEnumeration" with Fixed-at-Build access method, and TRUE value. Remove the PCD from the PciHostBridgeLibScan instance, and everything else that is useful only when the PCD is FALSE. In practice, this removes the PciHostBridgeUtilityGetRootBridges() function call, which is based on fw-cfg; see "OvmfPkg/Library/PciHostBridgeUtilityLib/PciHostBridgeUtilityLib.c". (Note that the dependency on PciHostBridgeUtilityLib remains in place, given that the PciHostBridgeLibScan instance continues using lower-level functions from the library that do not depend on fw-cfg.)
