cpuidle : consolidate arm drivers

Registered by Daniel Lezcano

This Blueprint has been moved to JIRA: https://cards.linaro.org/browse/PMWG-18

In order to create a single driver, we need to consolidate the different drivers to have a common pattern we can factor out to the cpuidle framework or a single arm driver.
