cxl/mem: Convert partition-info to resources
To date the per-device-partition DPA range information has only been
used for enumeration purposes. In preparation for allocating regions
from available DPA capacity, convert those ranges into DPA-type resource
trees.
With resources and the new add_dpa_res() helper some open coded end
address calculations and debug prints can be cleaned.
The 'cxlds->pmem_res' and 'cxlds->ram_res' resources are child resources
of the total-device DPA space and they in turn will host DPA allocations
from cxl_endpoint_decoder instances (tracked by cxled->dpa_res).
