Convert of_add_memory parsing to make use of of_address_to_resource

Haven't investigated further yet, but this one breaks my loco board
with:

It looks like the memory cannot be found anymore.
Ok, I just reworked Marvell Dove to boot from DT. I will have a look at
loco code to get an impression of how of_add_memory should be called
and add that to Dove. Maybe I can reproduce it there too.
