`GIC_PRIO_PSR_I_SET` was used to keep track of sections of the kernel
where interrupts always need to reach the CPU and could not be masked
via interrupt priorities, or DAIF bypassed the status of the PMR.

This flag unmasked IRQs when OR'd to GIC_PRIO_IRQON and ensured that
that IRQs were seen as disabled by the `local_irqs_...` functions,
as they would only check the PMR if pseudo-NMIs were enabled.

This is not needed anymore as our IRQ masking APIs now know how to handle
interrupt priorities properly and in parallel with DAIF : remove it.

It seems that the reviewed-by for v1 is missing.

I think you had some comments on v1 [1], so I didn't want to apply the
tag prematurely
