Álvaro Fernández Rojas 2b1c6b21b5 brcm2708: update linux 4.4 patches to latest version 
As usual these patches were extracted and rebased from the raspberry pi repo:
https://github.com/raspberrypi/linux/tree/rpi-4.4.y

Also adds support for Raspberry Pi Compute Module 3 (untested).

Subject: [PATCH] BCM270X_DT: Sound DT adjustments for Dynamic DT
There are a number of issues when loading and unloading overlays for
sound cards:
1) The "sound" and "audio" nodes must be children of a bus node, such
as "/soc", otherwise the DT changes don't result in platform devices
being created and deleted.
2) The "/sound" node must have a "disabled" status property, otherwise
setting the status to "okay" won't be detected.
3) ALSA doesn't like having components unloaded under its feet, and it
is easy to deadlock or crash. Ordering the overlay fragments so that
the sound card appears last avoids this problem.
