ARM: SoC fixes

Browse Source 
Here are a couple of bugfixes for v4.8-rc. Most of them have
 actually been around for a while this time but for some reason
 didn't get applied early on. The shmobile regulator fix is the
 only one that isn't completely obvious.
 
 device tree changes:
 - archtimer interrupts must be level triggered (multiple platforms)
 - fix for USB and MMC clocks on STiH410
 - fix split DT repository in case of raspberry-pi 3
 - A new use of skeleton.dtsi on arm64 has crept in after that
   was removed.
 
 defconfig updates:
 - xilinx vdma has a new Kconfig symbol name
 - keystone requires CONFIG_NOP_USB_XCEIV since v4.8-rc1
 
 code fixes:
 - fix regulator quirk on shmobile
 - suspend-to-ram regression on EXYNOS
 
 maintainer updates:
 - Javier Martinez Canillas is now a reviewer for Samsung EXYNOS
