[PATCH BlueZ 5/7] adapter: Add support for PHY Configuration Changed event

[Ayush Garg <ayush.garg@samsung.com>]

This change will subscribe the MGTM PHY Configuration
Changed event. This event will come whenever the controller
PHYs changed. Upon receiving the event, it will notify the
user by emitting "PhyConfiguration" property changed event.
