Huacai Chen fb7a8da0d7 net: stmmac: dwmac-loongson: Add new multi-chan IP core support
Add a new multi-chan IP core (0x12) support which is used in Loongson-
2K3000/Loongson-3B6000M. Compared with the 0x10 core, the new 0x12 core
reduces channel numbers from 8 to 4, but checksum is supported for all
channels.

Add a "multichan" flag to loongson_data, so that we can simply use a
"if (ld->multichan)" condition rather than the complicated condition
"if (ld->loongson_id == DWMAC_CORE_MULTICHAN_V1 || ld->loongson_id ==
DWMAC_CORE_MULTICHAN_V2)".
