Make FDT blob compatible with Raspberry Pi firmware.

Rasperry Pi firmware has a set of hardcoded pathes it uses to fill
FDT with system-specific information like display resolution, memory
size, UART and SDHCI clocks, ethernet MAC address. Handle two of them:

- Add placeholder for ethernet MAC address
- Move display node out of "axi" node
