ARM: imx: cpuidle: use init/exit common routine
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.
