[PATCH 2/5] Add fast connectable to hciops

[Dmitriy Paliy <dmitriy.paliy@nokia.com>]

Fast connectable switches between two sets of parameters to enable
or disable fast page scan mode. Page scan interval and page scan
type are changed to speed up connectabily when needed. When
disabled it sets default values. List of btd_adapter_ops is updated
respectively.
