Based on IP core classification, loongson has two devices,
0x37 is gmac, 0x10 is gnet, and the current device is gmac.

Difference:
device    type    pci_id    ip_core
ls7a1000  gmac    7a03      0x35/0x37
ls2k1000  gmac    7a03      0x37
ls7a2000  gnet    7a13      0x37
ls2k2000  gnet    7a13      0x10

The ref/ptp clock of gmac is 125000000. gmac device only
has a MAC chip inside and needs an external PHY chip;
