[PATCH V4 2/2] ARM: at91: cpuidle: Move driver to drivers/cpuidle

[Daniel Lezcano]

As the cpuidle driver code has no more the dependency with the pm code, the
'standby' callback being passed as a parameter to the device's platform data,
we can move the cpuidle driver in the drivers/cpuidle directory.
