brcm2708: add linux 4.4 support
- random-bcm2708 and spi-bcm2708 have been removed. - sound-soc-bcm2708-i2s has been upstreamed as sound-soc-bcm2835-i2s. Let's keep linux 4.1 for a while, since linux 4.4 appears to have some issues with multicast traffic on RPi ethernet: https://gist.github.com/Noltari/5b1cfdecce5ed4bc08fd Signed-off-by: Álvaro Fernández Rojas <noltari@gmail.com> SVN-Revision: 48266
