[PATCH net-next 1/3] stmmac: loongson: Remove surplus loop

[Philipp Stanner <phasta@kernel.org>]

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.
