Bluetooth: Add basic HCI definitions

Browse source 
For performing a basic HCI initialization procedure we need
definitions for the related HCI commands and events. This patch adds
these into separate hci.h header file. More content will be added to
this file as corresponding functionality gets added to other areas of
the stack.
