CoreLocateDevicePath is used in CoreInstallMultipleProtocolInterfaces to check if a Device Path Protocol instance with the same device path is alreay installed. CoreLocateDevicePath is a generic API, and would introduce some unnecessary overhead for such usage. The optimization is: 1. Implement IsDevicePathInstalled to loop all the Device Path Protocols installed and check if any of them matchs the given device path. 2. Replace CoreLocateDevicePath with IsDevicePathInstalled in CoreInstallMultipleProtocolInterfaces. This optimization could save several seconds in PCI enumeration on a system with many PCI devices.
