of/net: Move of_get_mac_address() to a common source file. There are two identical implementations of of_get_mac_address(), one each in arch/powerpc/kernel/prom_parse.c and arch/microblaze/kernel/prom_parse.c. Move this function to a new common file of_net.{c,h} and adjust all the callers to include the new header.

net: core: add of_find_net_device_by_node() Add a helper function which allows getting the struct net_device pointer associated with a given struct device_node pointer. This is useful for instance for DSA Ethernet devices not backed by a platform_device, but a PCI device. Since we need to access net_class which is not accessible outside of net/core/net-sysfs.c, this helper function is also added here and gated with CONFIG_OF_NET. Network devices initialized with SET_NETDEV_DEV() are also taken into account by checking for dev->parent first and then falling back to checking the device pointer within struct net_device.
