Johan Hovold 6945795bc8 Bluetooth: fix use-bdaddr-property quirk 
Devices that lack persistent storage for the device address can indicate
this by setting the HCI_QUIRK_INVALID_BDADDR which causes the controller
to be marked as unconfigured until user space has set a valid address.

The related HCI_QUIRK_USE_BDADDR_PROPERTY was later added to similarly
indicate that the device lacks a valid address but that one may be
specified in the devicetree.

As is clear from commit 7a0e5b15ca ("Bluetooth: Add quirk for reading
BD_ADDR from fwnode property") that added and documented this quirk and
commits like de79a9df16 ("Bluetooth: btqcomsmd: use
HCI_QUIRK_USE_BDADDR_PROPERTY"), the device address of controllers with
this flag should be treated as invalid until user space has had a chance
to configure the controller in case the devicetree property is missing.

As it does not make sense to allow controllers with invalid addresses,
restore the original semantics, which also makes sure that the
implementation is consistent (e.g. get_missing_options() indicates that
the address must be set) and matches the documentation (including
comments in the code, such as, "In case any of them is set, the
controller has to start up as unconfigured.").

Fixes: e668eb1e15 ("Bluetooth: hci_core: Don't stop BT if the BD address missing in dts")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
