I think the name of that property should make clear it's only changing
the interrupt output driver configuration. What about
"microchip,irq-active-high"?
Also, patch 3/3, which documents this new property, can be squashed into
this one.

This register controls a lot more details than that. Overriding it with
0 doesn't seem right. Please use regmap_update_bits() to just update
ALT_POL, and also add a #define for it, so the next reader knows what
the code is doing :)
