[PATCH net-next 1/3] net: stmmac: dwmac-loongson: Move queue number init to common function

[Huacai Chen]

Currently, the tx and rx queue number initialization is duplicated in
loongson_gmac_data() and loongson_gnet_data(), so move it to the common
function loongson_default_data().

This is a preparation for later patches.
