ARM: arm-soc soc updates, take 2 

This is the second batch of SoC updates for the 3.6 merge window,
 containing parts that arrived close to the merge window opening and
 thus needed to sit in linux-next for a while.
 
 Most contents is updates of Renesas shmobile, with a couple of
 Samsung Exynos patches in the mix.
