btw, the reason here is that when you call devm_ioremap_resource(), that
will call resource_size() which does:
size = res->end - res->start - 1;
so you need this extra 1 on the size when passing it via DT.

weird, on my TRM I see for dwc3 but 2 PHYs.

alright, but we should still pass the PHY right ? once silicon comes,
we want this to work without any further changers.
