net: stmmac: dwmac-loongson: Init ref and PTP clocks rate

[ Upstream commit c70f3163681381c15686bdd2fe56bf4af9b8aaaa ]

Reference and PTP clocks rate of the Loongson GMAC devices is 125MHz.
(So is in the GNET devices which support is about to be added.) Set
the respective plat_stmmacenet_data field up in accordance with that
so to have the coalesce command and timestamping work correctly.
