Routine Description:
This function is used to register the PCI device to the EFI,
create a handle for this PCI device,then attach apporpriate protocols
onto the handle.
This function registers the PCI IO device. It creates a handle for this PCI IO device
(if the handle does not exist), attaches appropriate protocols onto the handle, does
necessary initialization, and sets up parent/child relationship with its bus controller.
Arguments:
Controller - An efi handle.
PciIoDevice - A pointer to the PCI_IO_DEVICE.
Handle - A pointer to a efi handle.
Controller - An EFI handle for the PCI bus controller.
PciIoDevice - A PCI_IO_DEVICE pointer to the PCI IO device to be registered.
Handle - A pointer to hold the EFI handle for the PCI IO device.
Returns:
None
EFI_SUCCESS - The PCI device is successfully registered.
Others - An error occurred when registering the PCI device.
