dma-mapping: explicitly wire up ->mmap and ->get_sgtable
While the default ->mmap and ->get_sgtable implementations work for the
majority of our dma_map_ops impementations they are inherently safe
for others that don't use the page allocator or CMA and/or use their
own way of remapping not covered by the common code. So remove the
defaults if these methods are not wired up, but instead wire up the
default implementations for all safe instances.
Fixes: e1c7e324539a ("dma-mapping: always provide the dma_map_ops based implementation")
