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 126/127] SDIO-overlay: add bus_width parameter
+
+Allow setting of the SDIO bus width capability of the bcm2835-mmc
+host.  This is helpful when only a 1 bit wide bus is connected
+between host and device but both host and device advertise 4 bit
+mode.
