[PATCH] dmaengine: Update documentation for inline wrappers

[Geert Uytterhoeven]

During the last few years, several inline wrappers for DMA operations have
been introduced:
  - commit 16052827d98fbc13c31ebad560af4bd53e2b4dd5 ("dmaengine/dma_slave:
    introduce inline wrappers"),
  - commit a14acb4ac2a1486f6633c55eb7f7ded07f3ec9fc ("DMAEngine: add
    dmaengine_prep_interleaved_dma wrapper for interleaved api"),
  - commit 6e3ecaf0ad49de0bed829d409a164e7107c02993 ("dmaengine: add
    wrapper functions for device control functions").

Update the documentation to use the wrappers.
