sh: dma: fix kconfig dependency for G2_DMA
When G2_DMA is enabled and SH_DMA is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for SH_DMA_API Depends on [n]: SH_DMA [=n] Selected by [y]: - G2_DMA [=y] && SH_DREAMCAST [=y] The reason is that G2_DMA selects SH_DMA_API without depending on or selecting SH_DMA while SH_DMA_API depends on SH_DMA. When G2_DMA was first introduced with commit 40f49e7ed77f ("sh: dma: Make G2 DMA configurable."), this wasn't an issue since SH_DMA_API didn't have such dependency, and this way was the only way to enable it since SH_DMA_API was non-visible. However, later SH_DMA_API was made visible and dependent on SH_DMA with commit d8902adcc1a9 ("dmaengine: sh: Add Support SuperH DMA Engine driver"). Let G2_DMA depend on SH_DMA_API instead to avoid Kbuild issues.

This enables support for the DMA controller for the Dreamcast's
G2 bus. Drivers that want this will generally enable this on
