Laszlo Ersek 8af38170b5 OvmfPkg/PciHostBridgeLibScan: clean up file names and file-top comments
Rename "XenSupport.c" to "ScanForRootBridges.c", after the main function
in it.

Update the file-top comments; refer to both Bhyve and Xen.

Laszlo Ersek 4c81178cf0 OvmfPkg/PciHostBridgeLibScan: remove PcdOvmfHostBridgePciDevId
The "OvmfPkg/Library/PciHostBridgeLibScan/PciHostBridgeLibScan.inf"
instance is used in the following platforms in edk2:

  OvmfPkg/Bhyve/BhyveX64.dsc
  OvmfPkg/OvmfXen.dsc

Neither Bhyve nor Xen provide a Q35 board, therefore the expression

  PcdGet16 (PcdOvmfHostBridgePciDevId) != INTEL_Q35_MCH_DEVICE_ID

always evaluates to TRUE, in the PciHostBridgeLibScan instance.

Replace the expression with constant TRUE, eliminating the PCD dependency.

(In effect, this reports that the root bridge being registered does not
support extended PCI config space.)

Laszlo Ersek 33d4f3e39e 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.)

Laszlo Ersek e120c962f5 OvmfPkg/PciHostBridgeLibScan: create from PciHostBridgeLib
Create an almost verbatim copy of the
"OvmfPkg/Library/PciHostBridgeLib/PciHostBridgeLib.inf" library instance.

The new PciHostBridgeLibScan instance will ultimately duplicate a
negligible amount of code from the original, and will be used by the Bhyve
and OvmfXen platforms.

List the new driver in "Maintainers.txt", in the "OvmfPkg: bhyve-related
modules" and "OvmfPkg: Xen-related modules" sections.

This patch should be reviewed with "git show --find-copies-harder".
