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.
