[ Upstream commit 95f92928ad2215b5f524903e67eebd8e14f99564 ]

Add suspend/resum callback function in btusb_data which are reserved
for vendor specific usage during suspend/resume. hdev->suspend will be
added before stop traffic in btusb_suspend and hdev-> resume will be
added after resubmit urb in btusb_resume.
