dma-mapping: fix DMA_OPS dependencies
Driver that select DMA_OPS need to depend on HAS_DMA support to work. The vop driver was missing that dependency, so add it, and also add a another depends in DMA_OPS itself. That won't fix the issue due to how the Kconfig dependencies work, but at least produce a warning about unmet dependencies.
