Bluetooth: add hci event notification
WORKAROUND: Temporary workaround for bluetooth enable. For specific hci events, operations are needed. So this patch adds event notification and its notifier registration. Change-Id: I6f8fe0b3b90c12d7f4fe35823d25b9fbdcd98d06 Signed-off-by: Seung-Woo Kim <sw0312.kim@samsung.com>
