dmaengine: dw-edma: Add callbacks to fill link list entries

Browse source

Introduce four new callbacks to fill link list entries in preparation for
replacing dw_(edma|hdma)_v0_core_start().

Filling link list entries is expected to become more complex, and without
this abstraction both eDMA and HDMA paths would need to duplicate the same
logic. Add fill-entry callbacks so the code can be shared cleanly between
eDMA and HDMA implementations.
