/**
  Internal worker function to writes a PCI configuration register.

  This function wraps EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.Pci.Write() service.
  It writes the PCI configuration register specified by Address with the
  value specified by Data. The width of data is specifed by Width.
  Data is returned.

  @param  Address The address that encodes the PCI Bus, Device, Function and
                  Register.
  @param  Width   The width of data to write
  @param  Data    The value to write.

  @return The value written to the PCI configuration register.
