dts: Add bindings for multicast hash bins and perfect filter entries
This change adds bindings for the number of multicast hash bins and perfect filter entries supported by the Synopsys EMAC. The Synopsys EMAC core is configurable at device creation time, and can be configured for a different number of multicast hash bins and a different number of perfect filter entries. The device does not provide a way to query these parameters, therefore parameters are required. The Altera Cyclone V SOC has support for 256 multicast hash bins and 128 perfect filter entries, and is different than what's currently provided in the stmmac driver.
