ARM: imx: add cpuidle support for i.mx6ul This patch enables cpuidle driver for i.MX6UL, it reuses i.MX6SX's cpuidle driver, 3 levels of cpuidle supported: 1. ARM WFI; 2. SOC in WAIT mode; 3. SOC in WAIT mode + ARM power off. As i.MX6UL has cortex-A7 CORE with an internal L2 cache, so flushing it before powering down ARM platform is necessary, flush_cache_all() in last step of cpu_suspend has very small overhead, just call it to avoid cache type check for different platforms.
