raspberrypi4: Fix WiFi
Apply patch from branch master of meta-raspberrypi as a bbappend to recipe linux-firmware-rpidistro to fix WiFi on Raspberry Pi 4. This is a temporary solution while AGL master is still based on Thud. As soon as AGL moves to newer release of the Yocto Project and layer meta-raspberrypi this patch will become reduntant. The change of boardflags3 value from "0x48200100" to "0x44200100" has been done already in Raspbian (2019-06-20).

+Subject: [PATCH] brcmfmac43455-sdio.txt: Follow raspbian change for
+ boardflags3
+
+Without this change the WiFi interface on RPi4 never comes up. Also the
+upstream repository doesn't include this change. It is only (as far as I
+know) part of the raspberrypi deb repository with the following
+changelog:
+
+firmware-nonfree (1:20190114-1+rpt2) buster; urgency=medium
+ * Update brcmfmac43455-sdio.txt
+ - Update boardflags3
