pbdrv/bluetooth: Add classic runloop.

The classic runloop is separated from the LE one because little code
will be shared between them. For now, it's just a skeleton.

pbdrv/bluetooth: Classic init in async mode.

This allows use of the async get_version_info functions
to allow detecting the bluetooth controller version.
(Assuming we can get that working. For now, it's hardcoded.)
