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] gpio-poweroff: Allow it to work on Raspberry Pi
+
+The Raspberry Pi firmware manages the power-down and reboot
+process. To do this it installs a pm_power_off handler, causing
+the gpio-poweroff module to abort the probe function.
+
+This patch introduces a "force" DT property that overrides that
+behaviour, and also adds a DT overlay to enable and control it.
+
+Note that running in an active-low configuration (DT parameter
+"active_low") requires a custom dt-blob.bin and probably won't
+allow a reboot without switching off, so an external inversion
+of the trigger signal may be preferable.
