This patch renames the internal header for af802154. This naming

There are some old Bluetooth modules from Silicon Wave and Broadcom
which support Inquiry Result with RSSI, but do not advertise it. The
core has quirks in the code to enable that inquiry mode. However as
it stands right now, that code is not even executed since entering
the function to determine which inquiry mode requires that the device
has the feature bit for Inquiry Result with RSSI set in the first
place. So this makes this dead code that hasn't work for a long
time.

In conclusion, just remove these extra quirks and simplify the setup
of the inquiry mode to be inline and with that a lot easier to read
and understand.

The Roper Class 1 Bluetooth Dongle is another device that claims to
support Bluetooth 1.2 specification, but does not support the HCI
command for reading the local supported commands.

  < HCI Command: Read Local Version Information (0x04|0x0001) plen 0
  > HCI Event: Command Complete (0x0e) plen 12
      Read Local Version Information (0x04|0x0001) ncmd 1

      LMP Version: 1.2 (0x2) LMP Subversion: 0x757
      Manufacturer: Silicon Wave (11)

It clearly claims Bluetooth 1.2 support and in that regard has the
same issue as the AVM BlueFritz! USB devices (Silicon Wave based),
but the HCI Read Local Supported Commands command fails.

  < HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0
  > HCI Event: Command Status (0x0f) plen 4
      Read Local Supported Commands (0x04|0x0002) status 0x01 ncmd 1

the failing command will be skipped.

When the Bluetooth controllers requires an unconfigured state (for
example when the BD_ADDR is missing), then it is important to try
to register the SMP channels when the controller transitions to the
configured state.

This also fixes an issue with the debugfs entires that are not present
for controllers that start out as unconfigured.

Testing cross-transport pairing that starts on BR/EDR is only valid when
using a controller with BR/EDR Secure Connections. Devices will indicate
this by providing BR/EDR SMP fixed channel over L2CAP. To allow testing
of this feature on Bluetooth 4.0 controller or controllers without the
BR/EDR Secure Connections features, introduce a force_bredr_smp debugfs
option that allows faking the required AES connection.
