ARM: SoC: late fixes and dependencies

Browse Source 
This is a collection of a few late fixes and other misc. stuff that
 had dependencies on things being merged from other trees.
 
 The bulk of the changes are for samsung/exynos SoCs for some changes
 that needed a few minor reworks so ended up a bit late.  The others
 are mainly for qcom SoCs: a couple fixes and some DTS updates.
 
 There's one conflict with drivers/cpufreq/exynos-cpufreq.c because
 it's now been completely removed, but there were some fixes that hit
 mainline in the meantime.
