ARM: SoC fixes

Browse Source 
We've been sitting on our fixes branch for a while, so this batch is
 unfortunately on the large side.
 
 A lot of these are tweaks and fixes to device trees, fixing various bugs
 around clocks, reg ranges, etc. There's also a few defconfig updates
 (which are on the late side, no more of those).
 
 All in all the diffstat is bigger than ideal at this time, but the nothing
 in here seems particularly risky.
