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.

-bcm2709: Drop platform smp and timer init code
-
-irq-bcm2836 handles this through these functions:
-bcm2835_init_local_timer_frequency()
-bcm2836_arm_irqchip_smp_init()

-bcm270x: Use watchdog for reboot/poweroff
-
-The watchdog driver already has support for reboot/poweroff.
-Make use of this and remove the code from the platform files.
