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.

++                                addr pin is wired. (default=0x48 assumes addr
++                                is pulled to GND)
++        cha_enable              Enable virtual channel a.
++        cha_cfg                 Set the configuration for virtual channel a.
++                                (default=4 configures this channel for the
++                                voltage at A0 with respect to GND)
++        cha_datarate            Set the datarate (samples/sec) for this channel.
++                                (default=7 sets 860 sps)
++        cha_gain                Set the gain of the Programmable Gain
++                                Amplifier for this channel. (Default 1 sets the
++                                full scale of the channel to 4.096 Volts)
++
++        Channel parameters can be set for each enabled channel.
++        A maximum of 4 channels can be enabled (letters a thru d).
++        For more information refer to the device datasheet at:
