OvmfPkg: PciHostBridgeLib: install 64-bit PCI host aperture 

On the normal boot path (which is when PciHostBridgeDxe runs), the PCDs
have been calculated; report the 64-bit PCI host aperture to
PciHostBridgeDxe.

In the Ia32 build, the PCD values (zeros) come directly from the DEC file,
and this patch makes no difference.
