ARM: SoC fixes for 4.3-rc

Browse source 
Most of the changes this time are for incorrect device nodes in various
 ways, on on imx, berlin, exynos, ux500, uniphier, omap and meson.
 
 Chen-Yu Tsai now co-maintains mach-sunxi (Allwinner).
 
 Other bug fixes include
  * a partial revert of a broken tegra gpio patch
  * irq affinity for arm ccn
  * suspend on one Armada 385 machine
  * enable ZONE_DMA to avoid an OMAP crash for over 2GB RAM
  * turning on a regulator on beagleboard-x15 for HDMI
  * making the omap gpmc debug code visible
  * setup of orion network switch
  * a rare build regression for pxa
