Bluetooth: Add option for disabling legacy ioctl interfaces

Browse Source 
The legacy ioctl interfaces are only useful for BR/EDR operation and
since Linux 3.4 no longer needed anyway. This options allows disabling
them alltogether and use only management interfaces for setup and
control.

Enable support for legacy ioctl interfaces. This is only needed
for old and deprecated applications using direct ioctl calls for
controller management. Since Linux 3.4 all configuration and
setup is done via mgmt interface and this is no longer needed.
