mac80211: add pending brcmfmac patches fixing multiple interfaces

So far support for multiple interface was somehow broken in brcmfmac.
Driver couldn't correctly match firmware and system interfaces resulting
in not working APs and WARNINGs. This pending patches fixes that :)

+Subject: [PATCH] brcmfmac: consolidate ifp lookup in driver core
+
+In rx path the firmware provide an interface index which is used to
+map to a struct brcmf_if instance. However, this involves some trick
+that is done in two places. This is changed by having driver core
+providing brcmf_get_ifp() function.

+
+In brcmf_bus_start() the function brcmf_cfg80211_attach() is called which
+may fail. If this happens we should not call brcmf_cfg80211_detach() in
+the failure path as it will result in NULL pointer dereference:

+Subject: [PATCH] brcmfmac: correct detection of p2pdev interface event
+
+The p2pdev interface is setup in firmware resulting in a interface
+event. This event has role and no-if flag. When role is p2p client
+and no-if flag is set it indicates that this is the p2pdev interface.
+This info is used in handling the event and adding interface in the
+driver.

+ brcmf_txfinalize()
+
+Most call sites of brcmf_txfinalize already have struct brcmf_if
+instance so pass that to brcmf_txfinalize() as the function
+needs it anyway.

+Subject: [PATCH] brcmfmac: add mapping for interface index to bsscfg
+ index
+
+Because the P2P Device interface in firmware uses the same interface
+index as the primary interface we use the bsscfg index as index in the
+struct brcmf_pub::iflist. However, in the data path we get the interface
+index and not the bsscfg index. So we need a mapping of interface index
+to bsscfg index, which can be determined upon handle adding the interface.

+Subject: [PATCH] brcmfmac: add dedicated debug level for firmware
+ console logging
+
+Both PCIe and SDIO devices have the possibility to log the firmware
+console output in kernel log. For PCIe it is logged when PCIE debug
+level is enabled. For SDIO it is logged when user specifies a non-zero
+console interval through debugfs. This patch tries to make it a
+bit more consistent. The firmware console output is only logged when
+FWCON debug level is enabled.

+Subject: [PATCH] brcmfmac: introduce brcmf_net_detach() function
+
+In case of error during brcmf_bus_start() the network interfaces were
+freed using free_netdev(). However, the interfaces may have additional
+memory allocated which is not freed. The netdev has destructor set to
+brcmf_cfg80211_free_netdev() which frees the additional memory if
+allocated and call free_netdev(). The brcmf_net_detach() either calls
+brcmf_cfg80211_free_netdev() directly or uses unregister_netdev() when
+struct net_device::reg_state indicates the netdev was registered.
