As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.
This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.
The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

As always, this tends to be one of our bigger branches. There are lots of
updates this release, but not that many jumps out as something that needs
more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- More graphics DT pieces falling into place on Exynos, bridges, clocks.
- Plenty of DT updates for Qualcomm platforms for various IP blocks
- Some churn on Tegra due to switch-over to tool-generated pinctrl data
- Misc fixes and updates for Atmel at91 platforms
- Various DT updates to add IP block support on Broadcom's Cygnus platforms
- More updates for Renesas platforms as DT support is added for various IP
blocks (IPMMU, display, audio, etc).

to change the way the IRQ is triggered. When set,
the EDGE_IRQ quirk would change the irqflags used

In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an

This is really just duplicating the list of information that's
already available in the nl80211 attribute, so remove the list.
Two small changes are needed:
* remove STATION_INFO_ASSOC_REQ_IES complete, but the length
(assoc_req_ies_len) can be used instead
* add NL80211_STA_INFO_RX_DROP_MISC which exists internally
but not in nl80211 yet
This gets rid of the duplicate maintenance of the two lists.

In many cases, drivers can filter things like beacons that will
skew statistics reported by mac80211. To get correct statistics
in these cases, call drivers to obtain statistics and let them
override all values, filling values from mac80211 if the driver
didn't provide them. Not all of them make sense for the driver
to fill, so some are still always done by mac80211.
Note that this doesn't currently allow a driver to say "I know
this value is wrong, don't report it at all", or to sum it up
with a mac80211 value (as could be useful for "dropped misc"),
that can be added if it turns out to be needed.
This also gets rid of the get_rssi() method as is can now be
implemented using sta_statistics().

Silently ignore repetitive scheduling of recovery work and commands
being passed to the bus when the HW is not available. This can happen
many times during recovery and slow it down. It also spams the kernel
logs.

mac80211 unsets the default wep key on disassoc.
The fw doesn't support this notification, so simply
ignore it.
The actual flow actually triggers fw recovery in some
cases, as mac80211 unsets the default key only after
disassoc, when wlvif->sta.hlid, resulting in invalid
hlid being passed to the fw.

12xx chips allow only OFDM rates in AP mode for BT-Coex purposes. This
is no longer required in 18xx chips, starting with FW 8.6.0.0.8.
Update the min allowed FW version in 18xx to support this functionality.
