Adds helper functions to count HCI devs and process A2MP Discover
Request, code makes sure that first controller in the list is
BREDR one. Trace is shown below:
...
> ACL data: handle 11 flags 0x02 dlen 16
A2MP: Discover req: mtu/mps 670 mask: 0x0000
< ACL data: handle 11 flags 0x00 dlen 22
A2MP: Discover rsp: mtu/mps 670 mask: 0x0000
Controller list:
id 0 type 0 (BR-EDR) status 0x01 (Bluetooth only)
id 1 type 1 (802.11 AMP) status 0x01 (Bluetooth only)
