implementation of cpuidle driver for imx51

Registered by Yong on 2011-02-02

This blueprint has been superseded. See the newer blueprint "upstream i.mx platform cpuidle driver" for updated plans.

on freescale imx51, there is no cpuidle driver so far and it is better to have one for the sake of power management task.
