ARM: at91: cpuidle: Move driver to drivers/cpuidle
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. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Conflicts: drivers/cpuidle/Kconfig.arm drivers/cpuidle/Makefile
