Felix Fietkau 4224b52c3a 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 017/127] bcm2835-i2s: Eliminate debugfs directory error
Code ported from bcm2708-i2s driver in Raspberry Pi tree.
RPi commit fd7d7a3dbe9262d16971ef81c234ed28c6499dd7 ("bcm2708:
Eliminate i2s debugfs directory error")
Qualify the two regmap ranges uses by bcm2708-i2s ('-i2s' and '-clk')
to avoid the name clash when registering debugfs entries.
