[PATCH 068/228] cpufreq: imx6q: Use generic cpufreq routines

Most of the CPUFreq drivers do similar things in .exit() and .verify() routines and .attr. So its better if we have generic routines for them which can be used by cpufreq drivers then. This patch uses these generic routines for this driver.
