brcm2708: rename all patches from raspberrypi git tree to use 950 prefix

Right now all brcm2708 patches are extracted from the non-mainline
raspberrypi/linux git tree. Many of them are hacks and/or are unneeded
in LEDE. Raspberry Pi is getting better and better mainline support so
it would be nice to finally start maintaining patches in a cleaner way:
1) Backport patches accepted in upstream tree
2) Start using upstream drivers
3) Pick only these patches that are needed for more complete support

Handling above tasks requires grouping patches - ideally using the same
prefixes as generic ones. It means we should rename existing patches to
use some high prefix. This will allow e.g. use 0xx for backported code.

+Subject: [PATCH] BCM270X_DT: Add reference to audio_pins to CM dtb
+
+The CM1 dtb contains an empty audio_pins node, but no reference to it.
+Adding the usual pinctrl reference from the audio node enables the
+audremap overlay (and others) to easily turn on audio.
