This change adds some entropy to polling cycles, choosing the next
polling rf technology randomly. This reflects the change done in the
pn533 driver, avoiding possible infinite loop for devices that export 2
targets on 2 different modulations. If the first target is not
readable, we will stay in an error loop for ever.

- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
thus relies on the HCI stack. This submission provides support for tag
redaer/writer mode (including Type 5) and device tree bindings.
- PM runtime support and a bunch of bug fixes for TI's trf7970a.
- Device tree support for NXP's pn544. Legacy platform data support is
obviously kept intact.
- NFC Tag type 4B support to the NFC Digital stack.
- SOCK_RAW type support to the raw NFC socket, and allow NCI

Channels in 2.4GHz band overlap, this means that if we
send a probe request on channel 1 and then move to channel
2, we will hear the probe response on channel 2. In this
case, the RSSI will be lower than if we had heard it on
the channel on which it was sent (1 in this case).
The firmware / low level driver can parse the channel in
the DS IE or HT IE and compensate the RSSI so that it will
still have a valid value even if we heard the frame on an
adjacent channel. This can be done up to a certain offset.
Add this offset as a configuration for the low level driver.
A low level driver that can compensate the low RSSI in this
case should assign the maximal offset for which the RSSI
value is still valid.

In some cases, we need to force the association to be off in the
MAC_CONTEXT_CMD command we send to the firmware. Instead of having to
hack the vif->bss_conf.assoc value, pass it all the way down the call
chain.
Additionally, for the iwl_mvm_mac_ctxt_add() case, we *always* set
forced_assoc_off to true, so we can remove the hack in the d3 code
that was forcing it to off by hacking the bss_conf.assoc value.

Enabling beacon filtering should be done only after a beacon
has been received. Doing that too early will cause

Also, add the new get_expected_throughput() member

able to query the RC algorithm (this patch provides an
implementation of this API for both minstrel and
