Subject: [PATCH v2 1/3] dmaengine: Remove dma_device_satisfies_mask() wrapper

Commit aa1e6f1a385eb2b0 ("dmaengine: kill struct dma_client and
supporting infrastructure") removed the last user of the
dma_device_satisfies_mask() wrapper.

Remove the wrapper, and rename __dma_device_satisfies_mask() to
dma_device_satisfies_mask(), to get rid of one more function starting
with a double underscore.
