brcm2708: backport upstream ARM dts commits
This gets us in sync with dts from kernel 4.11. Two patches were already
backported earlier.
I decided to use 03x prefix as it's kind of similar to the 3xx prefix:
3xx - architecture specific patches
It isn't any documented or strict rule though. We don't need to stick to
it if we hit any problems.
