These helpers have had no callers until this series. I found the naming I initially used confusing and inconsistent. Rename fdma_dataptr_get_contiguous() and fdma_dataptr_virt_get_contiguous() to fdma_dataptr_dma_addr_contiguous() and fdma_dataptr_virt_addr_contiguous(). This makes the pair symmetric and clarifies what type of address each returns.
