[PATCH 08/17] Bluetooth: Move discovery macros to hci_core.h

[Andre Guedes <andre.guedes@xxxxxxxxxxxxx>]

Some of discovery macros will be used in hci_core so we need to
define them in common place such as hci_core.h. Thus, this patch
moves discovery macros to hci_core.h and also adds the DISCOV_
prefix to them.
