Merge branch 'timer_evtstrm' of git://linux-arm.org/linux-skn into clockevents/3.13
Adds support to configure the rate and enable the event stream for architected
timer. The event streams can be used to impose a timeout on a wfe, to safeguard
against any programming error in case an expected event is not generated or
even to implement wfe-based timeouts for userspace locking implementations.
This feature can be disabled(enabled by default).
Since the timer control register is reset to zero on warm boot, CPU PM notifier
is added to save and restore the value.
