[PATCH net-next] net: mtk_star_emac: use of_get_ethdev_address

[Rosen Penev]

The platform_ variant calls arch_get_platform_mac_address which is only
implemented under SPARC.

Switch to the of variant as of functions are used in the surrounding
code and to get EPROBE_DEFER support in order to handle NVMEM MAC
address specifications.
