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.
