Use core cpuidle timekeeping and irqen wrapper and remove that handling from this code.

Could the driver set en_core_tk_irqen to 1 and so let the core call the idle function? Is it to have the time measurement code closer to the low level idle code in ?__omap3_enter_idle?
Yes, Yes, and Yes.

Oops, thanks.
