Bluetooth: Add support for setting SSP debug mode
Enabling and disabling SSP debug mode is useful for development. This
adds a debugfs entry that allows to configure the SSP debug mode.
On purpose this has been implemented as debugfs entry and not a public
API since it is really only useful during testing and development.
