Isn't the reason the other way around? The PMIC generates a low-level
interrupt, but the GIC can only be configured to accept high-level (or
rising edge) and therefore the nvidia,invert-interrupt property needs to
be set in the PMC node?
One nitpick below.

I'd prefer to keep the properties grouped as before. interrupts is a
"client" property, whereas #interrupt-cells and interrupt-controller
are "provider" properties.
And I think the comment would be more appropriate in the pmc node, for
the same reason that I think the commit description isn't entirely
accurate.
