arm64: dts: exynos: gs101: Add 'local-timer-stop' to cpuidle nodes

In preparation for switching to the architected timer as the primary
clockevents device, mark the cpuidle nodes with the 'local-timer-stop'
property to indicate that an alternative clockevents device must be
used for waking up from the "c2" idle state.
