This change enables support to device initialization and to scan
process, by adding two new quirks for the following advertised but
unsupported commands: "Set Random Private Address Timeout" and
"Extended Create Connection".
It offers partial device support: controller initialization and scan.
The pairing process still needs work.
At the moment there is little to none available documentation about the
ATS2851 and its based USB dongles. It is known that it works in other
systems via generic drivers, and this is one step towards have it working
in Linux.

This one Im not so sure, if we can't set a timeout then we shouldn't
use the controller to rotate the RPA, although it seems we are already
doing it when the command bit is not set.

I guess we can incorporate the new quirk check inside use_ext_conn.

Hi Luiz, this propose is based on two observations:
- Another USB dongle I own here (fake CSR) initializes and works without
the command.
- The ATS2851 dongle initializes and works in other systems (as a generic
device) without the command.
I noticed there is a default timeout (HCI_DEFAULT_RPA_TIMEOUT) which
is set during the hci device allocation. I presume this is used when we
are unable to set the timeout.
