    drm/pagemap: Allocate folios when possible
    
    If the order is greater than zero, allocate a folio when populating the
    RAM PFNs instead of allocating individual pages one after the other. For
    example if 2MB folios are used instead of 4KB pages, this reduces the
    number of calls to the allocation API by 512.
