Bluetooth: Fix white list handling with resolvable private addresses
Devices using resolvable private addresses are required to provide
an identity resolving key. These devices can not be found using
the current controller white list support. This means if the kernel
knows about any devices with an identity resolving key, the white
list filtering must be disabled.
However so far the kernel kept identity resolving keys around even
for devices that are not using resolvable private addresses. The
notification to userspace clearly hints to not store the key and
so it is best to just remove the key from the kernel as well at
that point.
With this it easy now to detect when using the white list is
possible or when kernel side resolving of addresses is required.

Devices marked as reporting, direct connection (incoming) or general

In case the white list is full and can not hold all devices, the
white list is not used and the filter policy set to accept all

Bluetooth: Fix issue with ADV_IND reports and auto-connection handling
When adding remote devices to the kernel using the Add Device management
command, these devices are explicitly allowed to connect. This kind of
incoming connections are possible even when the controller itself is
not connectable.
For BR/EDR this distinction is pretty simple since there is only one
type of incoming connections. With LE this is not that simple anymore
since there are ADV_IND and ADV_DIRECT_IND advertising events.
The ADV_DIRECT_IND advertising events are send for incoming (slave
initiated) connections only. And this is the only thing the kernel
should allow when adding devices using action 0x01. This meaning
of incoming connections is coming from BR/EDR and needs to be
mapped to LE the same way.
Supporting the auto-connection of devices using ADV_IND advertising
events is an important feature as well. However it does not map to
incoming connections. So introduce a new action 0x02 that allows
the kernel to connect to devices using ADV_DIRECT_IND and in addition
ADV_IND advertising reports.
This difference is represented by the new HCI_AUTO_CONN_DIRECT value
for only connecting to ADV_DIRECT_IND. For connection to ADV_IND and
ADV_DIRECT_IND the old value HCI_AUTO_CONN_ALWAYS is used.

NFC: digital: Add 'tg_listen_md' and 'tg_get_rf_tech' driver hooks
The digital layer of the NFC subsystem currently
supports a 'tg_listen_mdaa' driver hook that supports
devices that can do mode detection and automatic
anticollision. However, there are some devices that
can do mode detection but not automatic anitcollision
so add the 'tg_listen_md' hook to support those devices.
In order for the digital layer to get the RF technology
detected by the device from the driver, add the
'tg_get_rf_tech' hook. It is only valid to call this
hook immediately after a successful call to 'tg_listen_md'.

Support for Initiator and Target mode with ISO18092 commands support:

- PSL_REQ/PSL_RES
- DEP_REQ/DEP_RES
Work based on net/nfc/digital_dep.c.
st21nfca is using:
- Gate reader F for P2P in initiator mode.
- Gate card F for P2P in target mode.
Felica tag and p2p are differentiated with NFCID2.
When starting with 01FE it is acting in p2p mode.
On complete_target_discovered on ST21NFCA_RF_READER_F_GATE

NFC: st21nfca: Implement stop_poll HCI hook
Send DM_DISCONNECT command to disconnect Terminal Host from the HCI network.
- The persistent states of the terminal host pipes, including registry values,
are not modifies. Therefore, there is no NVRAM update to disconnect the
terminal host.
- The terminal host RF card gates are disabled which means that there will be no event
related to card RF gates until communication has been restored.
- The terminal host RF reader request is reset so the RF reader polling for terminal
host is disabled.
To restore the communication, the terminal host can send any HCI command or event.

Add driver for STMicroelectronics ST21NFCB NFC controller.
ST21NFCB is using NCI protocol and a proprietary low level transport
protocol called NDLC used on top.
NDLC:
The protocol defines 2 types of frame:
- One type carrying NCI data (referred as DATAFRAME frames).
- One type carrying protocol information used for flow control and error
control mechanisms (referred as SUPERVISOR frames).
After each frame transmission to the NFC controller, the device host
SHALL waitfor an ACK (SUPERVISOR frame) reception before sending a
new frame.
The NFC controller MAY send a frame at anytime to the device host.
The NFC controller MAY send a specific WAIT supervisor frame to indicate
to device host that a NCI data packet has been received but that it could
take significant time before the NFC controller sends an ACK and thus
allows next data reception.
