Subject: [PATCH v7 0/2] Add support for Layerscape external interrupt lines

In v7, I've tried to change from a custom binding to use
interrupt-map, modelled on the recent addition of the
renesas,rza1-irqc (commits a644ccb819bc and 5e27a314a11f). It's
possible that the interrupt-map parsing code can be factored to a
common helper, but it's a bit hard to generalize from two examples to
know what a good interface would look like.

The interrupt-map-mask is a bit arbitrary. 0xff would likely work just
as well (but I think the ls2088a has 32 external lines, so it has to
be a least 0x1f).

Also, this drops the fsl,bit-reverse property and instead reads the
SCFGREVCR register to determine if bit-reversing is needed.

The dt/bindings patch now comes first in accordance with
Documentation/devicetree/bindings/submitting-patches.txt.
