db8e08a5a4 mac80211: brcm: backport first set of 5.4 brcmfmac changes 
This doesn't include 9ff8614a3dbe ("brcmfmac: use separate Kconfig file
for brcmfmac") due to a few conflicts with backports changes.

An important change is:
[PATCH 2/7] brcmfmac: change the order of things in brcmf_detach()
which fixes a rmmod crash in the brcmf_txfinalize().

529c95cc15 mac80211: brcmfmac: fix use-after-free & possible NULL pointer dereference 
1) Using fwctx variable after brcmf_fw_request_done() was executed meant
   accessing freed memory.
2) Using fwctx->completion for the wait_for_completion_timeout() call
   could reuslt in NULL pointer dereference on fw loading error or if
   brcmf_fw_request_done() was executed quickly enough.
