arm64: dts: stratix10: fix multicast filtering

commit fd5ba6ee3187617287fb9cb187e3d6b3631210a3 upstream

On Stratix 10, the EMAC has 256 hash buckets for multicast filtering. This
needs to be specified in DTS, otherwise the stmmac driver defaults to 64
buckets and initializes the filter incorrectly. As a result, e.g. valid
IPv6 multicast traffic ends up being dropped.
