This patch adds the bluetooth support for the brcm43438 module on the raspberrypi3 by
deploying the modules firmware and changing the targeting firmware path. In addition
the brcm43438.service adds the automatically attaching (hciattach) for systemd environments.
The following steps can be used to manually configure the brcm43438:
root@raspberrypi3:~# hciattach /dev/ttyAMA0 bcm43xx-3wire
bcm43xx_init
Flash firmware /lib/firmware/brcm/BCM43430A1.hcd
Set Controller UART speed to 3000000 bit/s
Device setup complete
