UBUNTU: SAUCE: Bluetooth: Add a load_firmware callback to struct hci_dev
 
From: Wen-chien Jesse Sung <jesse.sung@canonical.com>

BugLink: https://launchpad.net/bugs/1065400

load_firmware will be called at the end of hci_dev_open() if it
is defined. How, when, and the mutual exclusion for firmware loading
is inplemented in device driver.
