linux-firmware: restore and merge bluez-firmware

Browse Source 
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

@ -23,12 +23,12 @@ For other uses it's recommended to base images on `core-image-minimal` or
`core-image-base` as appropriate. The old image names (`rpi-hwup-image` and
`rpi-basic-image`) are deprecated.
## WiFi firmware blobs
## WiFi and Bluetooth Firmware
Be aware that the WiFi firmwares for the supported boards are not provided by
`linux-firmware` but by a custom recipe which only packages the needed blobs
for these boards. This is because the upstream `linux-firmware` doesn't support
or has outdated files for the blobs we need. The recipe
`linux-firmware-raspbian` is based on a fork of `linux-firmware` which
includes everything we need in order to fully support the WiFi hardware. All
machines define `MACHINE_EXTRA_RRECOMMENDS` accordingly.
Be aware that the WiFi and Bluetooth firmware for the supported boards
is not available in the base version of `linux-firmware` from OE-Core
(poky). The files are added from Raspbian repositories in this layer's
bbappends to that recipe. All machines define
`MACHINE_EXTRA_RRECOMMENDS` to include the required wireless firmware;
raspberrypi3 supports 3, 3B, and 3B+ and so include multiple firmware
packages.
