The Designware ethernet controller is also seen on PCI bus, e.g.
on Intel Quark SoC. Add this support in the DM version driver.

Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

---

Changes in v4: None
Changes in v3:
- Change to use dm_pci_read_config32()

Changes in v2:
- Change to use device_is_on_pci_bus()

Does this patch look OK to you?

Bin, perhaps (later) we should add a dm_pci_mem_to_phys(struct udevice *...) ?
