Bluetooth: btmrvl: use cal-data from device-tree instead of conf file

Some ARM versions of Chromebook need to download a new calibration

Bluetooth: Fix limited discoverable mode for Zeevo modules

There is an old Panasonic module with a Zeevo chip in there that is
not really operating according to Bluetooth core specification when
it comes to setting the IAC LAP for limited discoverable mode.

For reference, this is the vendor information about this module:

  < HCI Command: Read Local Version Information (0x04|0x0001) plen 0
  > HCI Event: Command Complete (0x0e) plen 12
        Read Local Version Information (0x04|0x0001) ncmd 1
          Status: Success (0x00)
          HCI version: Bluetooth 1.2 (0x02) - Revision 196 (0x00c4)
          LMP version: Bluetooth 1.2 (0x02) - Subversion 61 (0x003d)
          Manufacturer: Zeevo, Inc. (18)

The module reports only the support for one IAC at a time. And that
is totally acceptable according to the Bluetooth core specification
since the minimum supported IAC is only one.

  < HCI Command: Read Number of Supported IAC (0x03|0x0038) plen 0
  > HCI Event: Command Complete (0x0e) plen 5
        Read Number of Supported IAC (0x03|0x0038) ncmd 1
          Status: Success (0x00)
          Number of IAC: 1

The problem arises when trying to program two IAC into the module
on a controller that only supports one.

  < HCI Command: Write Current IAC LAP (0x03|0x003a) plen 7
          Number of IAC: 2
          Access code: 0x9e8b00 (Limited Inquiry)
          Access code: 0x9e8b33 (General Inquiry)
  > HCI Event: Command Status (0x0f) plen 4
        Write Current IAC LAP (0x03|0x003a) ncmd 1
          Status: Unknown HCI Command (0x01)

While this looks strange, but according to the Bluetooth core
specification it is a legal operation. The controller has to
ignore the other values and only program as many as it supports.

  This command shall clear any existing IACs and stores Num_Current_IAC
  and the IAC_LAPs in to the controller. If Num_Current_IAC is greater
  than Num_Support_IAC then only the first Num_Support_IAC shall be
  stored in the controller, and a Command Complete event with error
  code Success (0x00) shall be generated.

This specific controller has a bug here and just returns an error. So
in case the number of supported IAC is less than two and the limited
discoverable mode is requested, now only the LIAC is written to
the controller.

  < HCI Command: Write Current IAC LAP (0x03|0x003a) plen 4
          Number of IAC: 1
          Access code: 0x9e8b00 (Limited Inquiry)
  > HCI Event: Command Complete (0x0e) plen 4
        Write Current IAC LAP (0x03|0x003a) ncmd 1
          Status: Success (0x00)

All other controllers that only support one IAC seem to handle this
perfectly fine, but this fix will only write the LIAC for these
controllers as well.

mac80211: don't cancel csa finalize work within stop_ap

The current channel switch code has a potential deadlock:
1) * cfg80211_stop_ap acquires wdev-lock
   * ieee80211_stop_ap calls cancel_work_sync for the csa_finalize_work,
     which acquires the associated worker-lock
2) * ieee80211_csa_finalize_work holds the worker-lock when run
   * it calls cfg80211_ch_switch_notify which will claim the wdev-lock,
     and also needs to claim the sdata-lock (which is the same as the
     wdev-lock) to modify the beacons.

It is sufficient to just set the channel switch active to false. If the
worker is running later, it will find the channel switch to not be
active anymore and returns immediately without changing anything.

Consecutive MCSes in [8*(NSS-1)->8*NSS[ have the same number NSS of
streams (except for MCS32 which is mishandled ATM).
ATM minstrel_ht uses MCS_GROUP_RATES in place of this 8 modulus.
This change replaces such occurences and by doing so allows for different
values of MCS_GROUP_RATES (e.g to cope with VHT MCS8,9).

mac80211: add min required channel definition field

Add a new field to ieee80211_chanctx_conf to indicate
the min required channel configuration.

Tuning to a narrower channel might help reducing
the noise level and saving some power.

The min required channel definition is the max of
all min required channel definitions of the interfaces
bound to this channel context.

In AP mode, use 20MHz when there are no connected station.
When a new station is added/removed, calculate the new max
bandwidth supported by any of the stations (e.g. 80MHz when
80MHz and 40MHz stations are connected).

In other cases, simply use bss_conf.chandef as the
min required chandef.

Notify drivers about changes to this field by calling
drv_change_chanctx with a new CHANGE_MIN_WIDTH notification.

mac80211: enable easier manipulation of VHT beamforming caps

of sounding dimensions cap as these can take any 3 bit value.

mac80211: move csa_chandef to sdata

There is no reason why we should have only one channel switch
announcement at a time for a single phy.  When support for channel
switch with multiple contexts and multiple vifs per context is
implemented, we will need the chandef data for each vif.  Move the
csa_chandef structure to sdata to prepare for this.

cfg80211: add an option to disable processing country IEs

Certain vendors may want to disable the processing of
country IEs so that they can continue using the regulatory
domain the driver or user has set.  Currently there is no
way to stop the core from processing country IEs, so add
support to the core to ignore country IE hints.

cfg80211: add flags to define country IE processing rules

802.11 cards may have different country IE parsing behavioural
preferences and vendors may want to support these. These preferences
were managed by the REGULATORY_CUSTOM_REG and the REGULATORY_STRICT_REG
flags and their combination. Instead of using this existing notation,
split out the country IE behavioural preferences as a new flag. This
will allow us to add more customizations easily and make the code more
maintainable.
