If NO_DMA=y:
ERROR: "dma_unmap_sg" [drivers/media/v4l2-core/videobuf2-dma-sg.ko] undefined!

VIDEOBUF2_DMA_SG cannot be enabled manually by the user, it's always
selected automatically by drivers that need it. Several of those drivers
already have an explicit dependency on HAS_DMA.
Make VIDEOBUF2_DMA_SG depend on HAS_DMA. This makes it easier to find
drivers that select VIDEOBUF2_DMA_SG without depending on HAS_DMA, as
Kconfig will give a warning.
