ARM and ARM64 are the only two architectures implementing
arch_cpu_idle_prepare() simply to call local_fiq_enable().

We have secondary_start_kernel() already calling local_fiq_enable() and
this is done a second time in arch_cpu_idle_prepare() in that case. And
enabling FIQs has nothing to do with idling the CPU to start with.

So let's introduce init_fiq_boot_cpu() to take care of FIQs on the boot
CPU and remove arch_cpu_idle_prepare(). This is now done a bit earlier
at late_initcall time but this shouldn't make a difference in practice
i.e. when FIQs are actually used.

What kind of review did you do when giving that attributation?
