All callers convert frame numbers (perhaps in turn derived from struct page_info pointers) to an address, just for the function to convert it back to a frame number (as the first step of paddr_to_pdx()). Replace the function by mfn_to_nid() plus a page_to_nid() wrapper macro. Replace call sites by the respectively most suitable one. While there also - introduce a !NUMA stub, eliminating the need for Arm (and potentially other ports) to carry one individually, - drop the (strictly speaking wrong) "pure" attribute from the function, - extend a condition in dump_numa() to make sure that none of the assertions would trigger for empty or (unlikely) single-page nodes (at the same time this also prevents the warning printk() to be issued for every empty [e.g. CPU-only] node).
