stmmac: loongson: Remove surplus loop
loongson_dwmac_probe() contains a loop which doesn't have an effect,
because it tries to call pcim_iomap_regions() with the same parameters
several times. The break statement at the loop's end furthermore ensures
that the loop only runs once anyways.
Remove the surplus loop.
