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.

dt/net: add helper function of_get_phy_mode It adds the helper function of_get_phy_mode getting phy interface from device tree.

of_net.h: Provide empty functions if OF_NET is not configured of_get_mac_address() and of_get_phy_mode() are only provided if OF_NET is configured. While most callers check for the define, not all do, and those who do require #ifdef around the code. For those who don't, the missing check can result in errors such as arch/powerpc/sysdev/tsi108_dev.c:107:3: error: implicit declaration of function 'of_get_mac_address' [-Werror=implicit-function-declaration] arch/powerpc/sysdev/mv64x60_dev.c:253:2: error: implicit declaration of function 'of_get_mac_address' [-Werror=implicit-function-declaration] Provide empty functions if OF_NET is not configured. This is safe because all callers do check the return values.
