Andre Przywara 5973f7507a irqchip/gic, gic-v3: Prevent GSI to SGI translations 
commit 544808f7e2 upstream.

At the moment the GIC IRQ domain translation routine happily converts
ACPI table GSI numbers below 16 to GIC SGIs (Software Generated
Interrupts aka IPIs). On the Devicetree side we explicitly forbid this
translation, actually the function will never return HWIRQs below 16 when
using a DT based domain translation.

We expect SGIs to be handled in the first part of the function, and any
further occurrence should be treated as a firmware bug, so add a check
and print to report this explicitly and avoid lengthy debug sessions.

Fixes: 64b499d8df ("irqchip/gic-v3: Configure SGIs as standard interrupts")
