Support for Intel BT USB driver

From: Tedd Ho-Jeong An <[email protected]>

These set of patches adds Intel BT USB support. The patch adds an extension to execute of vendor specific initialization at early stage (before normal BT controller initialization & after the USB is initialized).

- During the USB probe time, if the VID/PID are matched, it executes a vendor specific initialization routine and uses a vendor specific HCI event handler. When completed, the existing HCI event handler is restored.

- When vendor specific initialization completes, normal BT controller initialization continues.

The rest of patches are Intel specific implementation.
