[PATCH v5 16/26] Bluetooth: Limit fast connectable support to >= 1.2 controllers

[Johan Hedberg <johan.hedberg@gmail.com>]

From: Johan Hedberg <johan.hedberg@intel.com>

The HCI commands that are necessary for fast connectable mode are only
available from HCI specification version 1.2 onwards. This should be
reflected in the supported settings as well as error response for the
set_fast_connectable command when dealing with a < 1.2 capable
controller.
