dmaengine/dma_slave: introduce inline wrappers
Add inline wrappers for device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to hide new parameter from current users of affected interfaces. Convert current users to use new wrappers instead of direct calls. Suggested by Russell King [https://lkml.org/lkml/2012/2/3/269].
