Johan Hedberg 79696d3b34 Bluetooth: Redesign Bluetooth init API
We need to be able to perform the init procedure asynchronously
through a callback. The RX fiber is a good candidate to use for the
callback since it's not active in its normal operation before
drv->open has been called. In order to prepare for a future
bt_disable() API the init API is renamed from bt_init() to
bt_enable(). If a NULL pointer is given as the callback the API
behaves synchronously like the old bt_init().

Arkadiusz Lichwa d63811079f Bluetooth: Adjust update connection params over L2CAP
The slave may request a change to the connection parameters using
the L2CAP LE signaling channel if either the master or the slave
or both do not support the Connection Parameters Request procedure.
Therefore if local controller doesn't support this, the request
can be made for sure.
