[ Upstream commit b649082312dd1a4c3989bbdb7c25eb711e9b1d94 ]
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.
