Should be setting ALL PCIe interrupts to '2'?  As I think in general
we say these PCIe are 'active high'.  The only reason I would think
we would NOT do this is if they are shared with some external device
that is 'active low'.  If so we should comment that somewhere (maybe
in the .dts, maybe just in the commit message).

I'd assume the ones that are pinned out are pulled high on the board.
Active-low is normal, it's these non-pinned-out "external" interrupts
that are pulled low inside the SoC that are weird.
