net: stmmac: dwmac-loongson: Set clk_csr_i to 100-150MHz
Current clk_csr_i setting of Loongson STMMAC (including LS7A1000/2000
and LS2K1000/2000/3000) are copy & paste from other drivers. In fact,
Loongson STMMAC use 125MHz clocks and need 62 freq division to within
2.5MHz, meeting most PHY MDC requirement. So fix by setting clk_csr_i
to 100-150MHz, otherwise some PHYs may link fail.
