[PATCH 0/2] dmaengine: add dmaengine_prep_slave_sg_context() API

[Frank . Li]

Add dmaengine_prep_slave_sg_context() for consumers that need to pass
context value when preparing slave SG transfers.

This replaces direct use of the prep_slave_sg() callback context,
which is intended for DMA engine internal use only. Mark it as deprecated
in preparation for making DMA engine internals private.

The only current user is sound/soc/sprd/sprd-pcm-compress.c.
