[PULL 1/5] hw/ppc: e500: Add missing #address-cells and #size-cells in the eTSEC node

[David Gibson]

From: Bin Meng <bin.meng@windriver.com>

Per devicetree spec v0.3 [1] chapter 2.3.5:

The #address-cells and #size-cells properties are not inherited
from ancestors in the devicetree. They shall be explicitly defined.
If missing, a client program should assume a default value of 2
for #address-cells, and a value of 1 for #size-cells.

These properties are currently missing, causing the <reg> property
of the queue-group subnode to be incorrectly parsed using default
values.
