ppc: Fix /memory reg property

Browse Source 
Physical address and size were both using two cells instead of one,
and their order was wrong. This would happen to work for RAM < 4 GB,
since the clear high address bits would happen to match the zero-based
memory location. It would indicate a second bank of size zero though.

Switch the value order and use encode-phys in preparation for ppc64.

This tidies the output of the Haiku boot loader.

v2:
* Document TODOs for ppc64, requested by Alex.
