brcm2708: update against latest rpi-3.10.y branch

Update our copies of the brcm2708 patches to the latest rpi-3.10-y
rebased against linux-3.10.y stable (3.10.32). This should hopefully
make it easier for us in the future to leverage the raspberry/rpi-*
branches.

+Subject: [PATCH 120/174] ASoC: Add support for HifiBerry DAC
+
+This adds a machine driver for the HifiBerry DAC.
+It is a sound card that can
+be stacked onto the Raspberry Pi.
