Bluetooth: Add support for limited privacy mode
Introduce a limited privacy mode indicated by value 0x02 to the mgmt
Set Privacy command.
With value 0x02 the kernel will use privacy mode with a resolvable
private address. In case the controller is bondable and discoverable
the identity address will be used.
