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:

+Subject: [PATCH 001/127] smsx95xx: fix crimes against truesize
+
+smsc95xx is adjusting truesize when it shouldn't, and following a recent patch from Eric this is now triggering warnings.
+
+This patch stops smsc95xx from changing truesize.
