a08f06bb7a seq_file: Introduce DEFINE_SHOW_ATTRIBUTE() helper macro
The DEFINE_SHOW_ATTRIBUTE() helper macro would be useful for current
users, which are many of them, and for new comers to decrease code
duplication.

22b371cbb9 Bluetooth: introduce DEFINE_SHOW_ATTRIBUTE() macro
This macro deduplicates a lot of similar code across the hci_debugfs.c
module. Targeting to be moved to seq_file.h eventually.

5177a83827 Bluetooth: Add debugfs fields for hardware and firmware info
Some Bluetooth controllers allow for reading hardware and firmware
related vendor specific infos. If they are available, then they can be
exposed via debugfs now.

b55d1abf56 Bluetooth: Expose quirks through debugfs
This patch expose controller quirks through debugfs. It would be
useful for BlueZ tests using vhci. Currently there is no way to
test quirk dependent behaviour. It might be also useful for manual
testing.

b7cb93e528 Bluetooth: Merge hdev->dbg_flags fields into hdev->dev_flags
With the extension of hdev->dev_flags utilizing a bitmap now, the space
is no longer restricted. Merge the hdev->dbg_flags into hdev->dev_flags
to save space on 64-bit architectures. On 32-bit architectures no size
reduction happens.

cb0d2faeb1 Bluetooth: Fix scope of sc_only_mode debugfs entry
The sc_only_mode debugfs entry is used to read the current state of the
Secure Connections Only mode. Before Bluetooth 4.2 this mode was only
for BR/EDR controllers and with that tight to the support Secure Simple
Pairing. Since Secure Connections is now available for BR/EDR and LE
this debugfs entry is no longer correctly place.

Move it to the common section and enable it when either BR/EDR Secure
Connections feature is supported or when the controller has LE support.

91389af67c Bluetooth: Remove broken force_lesc_support debugfs option
The force_lesc_support debugfs option never really worked. It has a race
condition between creating the debugfs entry and registering the L2CAP
fixed channel for BR/EDR SMP support.

Also this has been replaced with a working force_bredr_smp debugfs
switch that developers can use now.

60c5f5fb1f Bluetooth: Add skeleton functions for debugfs creation
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
file hci_debugfs.c to centralize all debugfs file creation. For now
leave the current files in the core, but in the future all debugfs
file creation will be moved.
