    ath79: ja76pf2: use nvmem cells to specify MAC addresses
    
    The bootloader on this board hid the partition containig MAC addresses
    and prevented adding this space to FIS directory, therefore those had to
    be stored in RedBoot configuration as aliases to be able to assigne them
    to proper interfaces. Now that fixed partition size are used instead of
    redboot-fis parser, the partition containig MAC addresses could be
    specified, and with marking it as nvmem cell, we can assign them without
    userspace involvement.
