promote memory as I am not sure all the demotion cases are handled, however it is useful to implement pmap_page_set_memattr. This is used, for example, when mapping uncached memory for bus_dma(9). pmap_page_set_memattr needs to demote the DMAP region as on ARM we need to ensure all mappings to the same physical address have the same attributes.
