mac80211: Update to version 5.2-rc7

This updates mac80211 to version 5.2-rc7, this contains all the changes
to the wireless subsystem up to Linux 5.2-rc7.

* The removed patches are applied upstream
* b43 now uses kmod-lib-cordic
* Update the nl80211.h file in iw to match backports version.
* Remove the two backports from kernel 4.9, they were needed for mt76,
  but that can use the version from backports now, otherwise they
  collide and cause compile errors.

-Subject: [PATCH] mm: rename __alloc_page_frag to page_frag_alloc and
- __free_page_frag to page_frag_free
-
-Patch series "Page fragment updates", v4.
-
-This patch series takes care of a few cleanups for the page fragments
-API.
-
-First we do some renames so that things are much more consistent.  First
-we move the page_frag_ portion of the name to the front of the functions
-names.  Secondly we split out the cache specific functions from the
-other page fragment functions by adding the word "cache" to the name.
-
-Finally I added a bit of documentation that will hopefully help to
-explain some of this.  I plan to revisit this later as we get things
-more ironed out in the near future with the changes planned for the DMA
-setup to support eXpress Data Path.
-
-This patch (of 3):
-
-This patch renames the page frag functions to be more consistent with
-other APIs.  Specifically we place the name page_frag first in the name
-and then have either an alloc or free call name that we append as the
-suffix.  This makes it a bit clearer in terms of naming.
-
-In addition we drop the leading double underscores since we are
-technically no longer a backing interface and instead the front end that
-is called from the networking APIs.

-Subject: [PATCH] mm: rename __page_frag functions to __page_frag_cache, drop
- order from drain
-
-This patch does two things.
-
-First it goes through and renames the __page_frag prefixed functions to
-__page_frag_cache so that we can be clear that we are draining or
-refilling the cache, not the frags themselves.
-
-Second we drop the order parameter from __page_frag_cache_drain since we
-don't actually need to pass it since all fragments are either order 0 or
-must be a compound page.
