[0/3] dmaengine: xilinx: Better cyclic transfers

Hello,

So far all my testing was performed by looping the playback output to
the recording input and comparing the files using FFTs. Unfortunately,
when the DMA engine suffers from the same issue on both sides, some
issues may appear un-noticed. I now have proper hardware to really
listen to the actual sound, so here are a couple of fixes and
improvements.

Cheers,
Miquèl

  dmaengine: xilinx: xdma: Fix the count of elapsed periods in cyclic
    mode
  dmaengine: xilinx: xdma: Better handling of the busy variable
  dmaengine: xilinx: xdma: Add terminate_all/synchronize callbacks
