Yes the binding enforces this but this patch is removing that
enforcement and instead mandating that dp_com is always at index 1 (i.e.
the second one) so that we can add the DP serdes region directly after
and avoid adding yet another reg-names property. I changed the binding
for this usb3-dp phy compatible to make reg-names optional as well. I
don't see any gain from using reg-names.

Sure. I'll roll that into this patch.
