ARM: SoC platform changes for 3.19

Browse source 
New and updated SoC support, notable changes include:
 
 * bcm: brcmstb SMP support
 * bcm: initial iproc/cygnus support
 * exynos: Exynos4415 SoC support
 * exynos: PMU and suspend support for Exynos5420
 * exynos: PMU support for Exynos3250
 * exynos: pm related maintenance
 * imx: new LS1021A SoC support
 * imx: vybrid 610 global timer support
 * integrator: convert to using multiplatform configuration
 * mediatek: earlyprintk support for mt8127/mt8135
 * meson: meson8 soc and l2 cache controller support
 * mvebu: Armada 38x CPU hotplug support
 * mvebu: drop support for prerelease Armada 375 Z1 stepping
 * mvebu: extended suspend support, now works on Armada 370/XP
 * omap: hwmod related maintenance
 * omap: prcm cleanup
 * pxa: initial pxa27x DT handling
 * rockchip: SMP support for rk3288
 * rockchip: add cpu frequency scaling support
 * shmobile: r8a7740 power domain support
 * shmobile: various small restart, timer, pci apmu changes
 * sunxi: Allwinner A80 (sun9i) earlyprintk support
 * ux500: power domain support
 
 Overall, a significant chunk of changes, coming mostly from
 the usual suspects: omap, shmobile, samsung and mvebu, all of
 which already contain a lot of platform specific code in
 arch/arm.
