Add dma_set_mask(), dma_set_coherent_mask(), dma_map_sgtable(), and
dma_max_mapping_size() helpers to fix a build error when
CONFIG_HAS_DMA is not enabled.
Note that when CONFIG_HAS_DMA is enabled, they are included in both
bindings_generated.rs and bindings_helpers_generated.rs. The former
takes precedence so behavior remains unchanged in that case.
This fixes the following build error on UML:
