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().

+
+The function strcpy() is inherently not safe. Though the function
+works without problems here, it would be better to use other safer
+function, e.g. strlcpy(), to replace strcpy() still.

+The function chandef_to_chanspec() was not handling 160MHz bandwidth

+Subject: [PATCH 3/3] brcmfmac: allow 160MHz in custom regulatory rules
+
+The driver has custom regulatory rules which had maximum bandwidth
+for 5GHz channels set to 80MHz. As a consequence the driver can
+not use 160MHz in AP mode even when the device supports it. So
+relax the rules allowing 160MHz. After wiphy_register() the channel
+flags are updated according what the device actually supports.

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When brcmf_detach() from the bus layer upon rmmod we can no longer
+communicate. Hence we will set the bus state to DOWN and cleanup
+the event and protocol layer. The network interfaces need to be
+deleted before brcmf_cfg80211_detach() because the latter does the
+wiphy_unregister() which issues a warning if there are still network
+devices linked to the wiphy instance.

+Subject: [PATCH 7/7] brcmfmac: remove unnecessary strlcpy() upon obtaining
+ "ver" iovar
+
+Recently a strcpy() was replaced by strlcpy(). However, the strcpy()
+was not needed in the first place. So removing that line of code.
