intel/i210: Change API for function mainboard_get_mac_address()

The function mainboard_get_mac_address() is used to get a MAC address
    for a given i210 PCI device. Instead of passing pure numbers for PCI
    bus, device and function pass the device pointer to this function. In
    this way the function can retrieve the needed values itself as well as
    have the pointer to the device tree so that PCI path can be evaluated
    there.
