net: stmmac: dwmac-loongson: Add fix_soc_reset() callback

Browse source

commit f06e4bfd01 upstream.

Loongson's DWMAC device may take nearly two seconds to complete DMA reset,
however, the default waiting time for reset is 200 milliseconds.
Therefore, the following error message may appear:

[14.427169] dwmac-loongson-pci 0000:00:03.2: Failed to reset the dma
