The attempt to Raspbian updated firmware blobs in packages separate from
linux-firmware introduced unresolvable conflicts with the standard
linux-firmware roll-up package. Revert to using an augmented
linux-firmware recipe that overrides and adds firmware from two Raspbian
repositories that have up-to-date images.
Closes#244

Currently, we are installing the rpi custom txt and fw files whenever
the meta-raspberrypi layer is included in bblayers.conf. This breaks
other machines that need to use the bcm43430 drivers but with alternate
txt or fw files.
Install these files only when "rpi" is in MACHINEOVERRIDES.

The version of this firmware provided by linux-firmware is 7.45.41.26. This
version seems to have connectivity issues when bonding interfaces. Raspbian
included an updated version (7.45.41.46) which tested, proved to fix this
problem (see https://github.com/resin-os/meta-resin/issues/812).
The version Raspbian is providing is not yet in linux-firmware as they have it
directly from Cypress (see https://github.com/RPi-Distro/repo/issues/88).
Besides the issue described above, it fixes various other issues including a
broadpwn fix.
Hopefully this version, or a newer one, will end up in upstream soon. In order
to catch when that happens and stop overwriting this firmware, a check is added
in the racipe based on the md5sum of the current shipped firmware.
In terms of ditribution license, we got an informal one in the github thread
mentioned above.

Currently the firmware is installed but kernel fails to load it
due this .txt file missing in the firmware directory and it ends
up with wifi/bluetooth i/f not being initialized. The error is
also in dmesg
[ 3.120991] usbcore: registered new interface driver brcmfmac
[ 3.148240] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.txt failed with error -2
After applying this patch now ifconfig -a can list wlan0 interface
successfully.
