[PATCH v2 6/8] arm: prepare for instantiating different IRQ chip devices

[Andre Przywara]

Hi, contrary to my boasting in the cover letter I managed to
accidentially drop the fix for the GIC device initialization error
handling Will requested from this series.
If we fail the GIC initialization sequence at some point, we should
make sure to not let the gic_fd initialized, so that subsequent
accesses to the GIC device fail appropriately.
So the fix below should be merged in, actually a part of it already
in patch 2/8.
If there are no further comments, I will re-spin this series with
those fixes contained in the proper patches later this week.

Cheers,
Andre.
