Set the correct parent dev when registering hdev. This allows userspace
tools to find the parent device (for example, to set the power/wakeup
property).

Before this change, the path was /sys/devices/virtual/bluetooth/hci0
and after this change, it looks more like:
/sys/bus/mmc/devices/mmc1:0001/mmc1:0001:2/bluetooth/hci0
