Because without CONFIG_IPIPE local_irq_restore deals with FIQs
With CONFIG_IPIPE local_irq_restore does not deal with FIQs
We can of course rework local_irq_restore to take into account FIQs with
CONFIG_IPIPE, but that would make local_irq_restore heavier in a lot of
places, whereas there are in fact only three spots to fix, for only one SOC.
