ARM: arm-soc fixes for 3.9 

Only one remaining fix for arm-soc platforms at this time, a small
 bugfix for cpu hotplug on highbank platforms that has become much
 easier to hit as of late. Details in the patch description, but it's
 small and well-contained and definitely impacts users of the platform,
 so 3.9 seems appropriate.
