I would prefer not to make stmmac_main.c even larger by including bus
specific helpers there. We already have stmmac_pltfm.c for those which
use struct platform_device. The logical name would be stmmac_pci.c, but
that's already taken by a driver.

One way around that would be to rename stmmac_pci.c to dwmac-pci.c
(glue drivers tend to be named dwmac-foo.c) and then re-use
stmmac_pci.c for PCI-related stuff in the same way that stmmac_pltfm.c
is used.

Another idea would be stmmac_libpci.c.
