ARM: SoC fixes

Browse source 
A smallish batch of fixes, a little more than expected this late, but
 all fixes are contained to their platforms and seem reasonably low risk:
 
 - A somewhat large SMP fix for ux500 that still seemed warranted to include here
 - OMAP DT fixes for pbias regulator specification that broke due to some DT
   reshuffling
 - PCIe IRQ routing bugfix for i.MX
 - Networking fixes for keystone
 - Runtime PM for OMAP GPMC
 - A couple of error path bug fixes for exynos
