Won't this also relax the naming for all devices that allow a single
reset, but expect the stmmaceth one? I'm not sure that that actually
matters, I think the consumer bindings have constraints themselves.

Before commit 843f603762a5 ("dt-bindings: net: snps,dwmac: Add 'ahb'
reset/reset-name"), the 'stmmaceth' was the only possible option, hence
there was no need for any constraints on the consumer bindings.  But
afterwards it was allowed to use both resets, hence I think the bindings
should have been updated at that time by adding 'maxItems: 1' to prevent
using the 2nd reset.

I could fix this in a separate series, if it's not something mandatory
to be handled here.

If it is not introduced by this series, I don't see why it could not be
handled separately if needed.
