This patch introduces an independent cpuidle driver for i.MX6SX, and supports arm power off in idle, totally 3 levels of cpuidle are supported as below: 1. ARM WFI; 2. SOC in WAIT mode; 3. SOC in WAIT mode + ARM power off. ARM power off can save at least 5mW power. This patch also replaces imx6q_enable_rbc with imx6_enable_rbc.
