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] spi-bcm2835: Disable forced software CS
+
+Select software CS in bcm2708_common.dtsi, and disable the automatic
+conversion in the driver to allow hardware CS to be re-enabled with an
+overlay.
