The code intializes the cpuidle driver at different places.
The cpuidle driver for :
* imx5 : is in the pm-imx5.c, the init function is in cpuidle.c
* imx6 : is in cpuidle-imx6q.c, the init function is in cpuidle.c
and cpuidle-imx6q.c
Instead of having the cpuidle code spread across different files,
let's create a driver for each SoC and use the common register function.
