81b3039557 NFC: Set target nfcid1 for all HCI reader A targets
Without the discovered target nfcid1 and its length set properly, type 2
tags detection fails with the pn544 as it checks for them from
pn544_hci_complete_target_discovered().

With merge help from Antonio Quartulli (batman-adv) and
Stephen Rothwell (drivers/net/usb/qmi_wwan.c).

The net/mac80211/mlme.c conflict seemed easy enough, accounting for a
conversion to some new tracing macros.

01d719a228 NFC: Add ISO 14443 type B protocol
Some devices (e.g. Sony's PaSoRi) can not do type B polling, so we have
to make a distinction between ISO14443 type A and B poll modes.

8f50020ed9 NFC: LLCP late binding
With the LLCP 16 local SAPs we can potentially quickly run out of source
SAPs for non well known services.
With the so called late binding we will reserve an SAP only when we actually
get a client connection for a local service. The SAP will be released once
the last client is gone, leaving it available to other services.

ebbb16d9eb NFC: Forbid SSAP binding to a not well known LLCP service
With not Well Known Services there is no guarantees as to which
SSAP the server will be listening on, so there is no reason to
support binding to a specific source SAP.

cbbf472181 NFC: Release LLCP SAP when the owner is released
The LLCP SAP should only be freed when the socket owning it is released.
As long as the socket is alive, the SAP should be reserved in order to
e.g. send the right wks array when bringing the MAC up.

a10d595b10 NFC: Allow HCI driver to pre-open pipes to some gates
Some NFC chips will statically create and open pipes for both standard
and proprietary gates. The driver can now pass this information to HCI
such that HCI will not attempt to create and open them, but will instead
directly use the passed pipe ids.
