Steve Muckle 6370716bc3 sched: do not set window until sched_clock is fully initialized ...

The system initially uses a jiffy-based sched clock. When the platform
registers a new timer for sched_clock, sched_clock can jump backwards.
Once sched_clock_postinit() runs it should be safe to rely on it.

Also sched_clock_cpu() relies on completion of sched_clock_init()
and until that happens sched_clock_cpu() returns zero. This is used
in the irq accounting path which window-based stats relies upon.
So do not set window_start until sched_clock_cpu() is working.
