boot/efi: rework address-cells and size-cells handling

see Devicetree Specification,
section 2.3.5 #address-cells and #size-cells

The #address-cells and #size-cells properties may be used in any
device node that has children in the devicetree hierarchy and
describes how child device nodes should be addressed.

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.
