We do not want the service cache to be enabled indefinitely after
mgmt_read_info is called. To solve this a timer is added which will
automatically disable the cache if mgmt_set_dev_class isn't called
within 5 seconds of calling mgmt_read_info.

Due to the upcoming addition of a service cache timer the functions to
update the EIR and CoD need to be higher up in mgmt.c in order to avoid
unnecessary forward-declarations. This patch simply moves code around
without any other changes in order to make subsequent patches more
readable.

Instead of having an explicit service cache command we can make the mgmt
API simpler by implicitly enabling the cache when mgmt_read_info is
called for the first time and disabling it when mgmt_set_dev_class is
called.

This patch adds the dev_flags field to struct hci_dev. This new
flags variable should be used to define flags related to BR/EDR
and/or LE controller itself. It should be used to define flags
which represents states from the controller. The dev_flags is
cleared in case the controller sends a Reset Command Complete
Event to the host.
Also, this patch adds the HCI_LE_SCAN flag which was created to
track if the controller is performing LE scan or not. The flag
is set/cleared when the controller starts/stops scanning.
This is an initial effort to stop using hdev->flags to define
internal flags since it is exported to userspace by an ioctl.
