Bluetooth: hci_ll: add support for setting public address

This adds support for setting the public address on Texas Instruments
Bluetooth chips using a vendor-specific command.

This has been tested on a CC2560A chip. The TI wiki also indicates that
this command should work on TI WL17xx/WL18xx Bluetooth chips.

During review, there was some question as to the correctness of the byte
swapping since TI's documentation is not clear on this matter. This can
be tested with the btmgmt utility from bluez. The adapter must be powered
off to change the address. If the baswap() is omitted, address is reversed.

In case there is a issue in the future, here is the output of btmon during
the command `btmgmt public-addr 00:11:22:33:44:55`:

uvcvideo: Prevent new URBs being processed at stream stop

With asynchronous handling of the URBs from the USB Complete handler, we
get a continual stream of packets being received while we are attempting
to shutdown the stream.

Packets that have already been received and processed are on a
work-queue, but during stream shutdown the URBs that those packets
belong to are killed and free'd.

To prevent this race from causing invalid memory accesses, prevent new
URBs from being processed when uvc_stop_streaming() is called by
introducing a new flag "UVC_QUEUE_STOPPING" into the queue, and checking
this when processing the URB to be queued.

With this, we can flush the work queue, and commence a normal pipe
shutdown. Work tasks that are already queued are processed, but the URBs
are prevented from being re-submitted to the USB stack.
