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] i2c: bcm2835: Use dev_dbg logging on transfer errors
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Writing to an AT24C32 generates on average 2x i2c transfer errors per
+32-byte page write. Which amounts to a lot for a 4k write. This is due
+to the fact that the chip doesn't respond during it's internal write
+cycle when the at24 driver tries and retries the next write.
+Only a handful drivers use dev_err() on transfer error, so switch to
+dev_dbg() instead.
