All the drivers are using, in their initialization function, the
for_each_possible_cpu macro.

Using for_each_online_cpu means the driver must handle the initialization
of the cpuidle device when a cpu is up which is not the case here.

Change the macro to for_each_possible_cpu as that fix the hotplug
initialization and make the initialization routine consistent with the
rest of the code in the different drivers.

The en_core_tk_irqen flag is set in all the cpuidle driver which
means it is not necessary to specify this flag.

Remove the flag and the code related to it.

Use the CPUIDLE_FLAG_TIMER_STOP and let the cpuidle framework
to handle the CLOCK_EVT_NOTIFY_BROADCAST_ENTER/EXIT when entering
this state.

This patch adds the cpuidle driver for the ux500 SoC.
The boards saves 12mA with these states. It is based on the latest
cpuidle consolidation from Robert Lee.

The cpu can go to retention only if the other core is in WFI.

If the other cpu is in WFI and we decoupled the gic from the cores,
then we have the guarantee, it won't be wake up.

It is up to the prcmu firmware to recouple the gic automatically
after the power state mode is selected.
