Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20170613' into staging

target-arm queue:
 * vITS: Support save/restore
 * timer/aspeed: Fix timer enablement when reload is not set
 * aspped: add temperature sensor device
 * timer.h: Provide better monotonic time on ARM hosts
 * exynos4210: various cleanups
 * exynos4210: support system poweroff
