[PATCH v1 1/2] net: stmmac: add support for dwmac 3.72a

[Lothar Rubusch <l.rubusch@gmail.com>]

The dwmac 3.72a is an ip version that can be found on Intel/Altera Arria10
SoCs. Going by the hardware features "snps,multicast-filter-bins" and
"snps,perfect-filter-entries" shall be supported. Thus add a
compatibility flag, and extend coverage of the driver for the 3.72a.
