Avoid multiple attempts to create the debugfs entry, force_bredr_smp,
by moving it from the SMP registration to the BR/EDR controller init
section. hci_debugfs_create_bredr is only called when HCI_SETUP and
HCI_CONFIG is not set.

The BT qualification test SM/MAS/PKE/BV-01-C needs us to turn off
the MITM flag when pairing, and at the same time also set the io
capability to something other than no input no output.
Currently the MITM flag is only unset when the io capability is set
to no input no output, therefore the test cannot be executed.
This patch introduces a debugfs option to force MITM flag to be
turned off.

MGMT command is added to receive the list of blocked keys from
user-space.
The list is used to:
1) Block keys from being distributed by the device during
the ke distribution phase of SMP.
2) Filter out any keys that were previously saved so
they are no longer used.

The debugfs file creation has been part of the core initialization
handling of controllers. With the introduction of Bluetooth 4.2 core
specification, the number of debugfs files is increasing even further.
To avoid cluttering the core controller handling, create a separate

leave the current files in the core, but in the future all debugfs
file creation will be moved.
