dmaengine: Add dma_get_slave_caps() inline stub when !CONFIG_DMA_ENGINE
Commit 0d5484b1c3db8a38 ("dmaengine: Move dma_get_slave_caps()
implementation to dmaengine.c") turned the inline dma_get_slave_caps()
function into an external function without adding an inline stub for the
cases where CONFIG_DMA_ENGINE isn't set. This breaks compilation of
drivers using the DMA engine API when CONFIG_DMA_ENGINE isn't set.
Add an inline stub to fix compilation.
