hfp_hf_bluez5: Add support for Enabling/Disabling the modem

Now that we have the support for sending the correct messages
to BlueZ, we are able to dynamically power up/down the HFP modem.

We add another property to the modem to be able to get the D-Bus
object path that represents the remote device.
