In pd_tx_submit(), variable ‘cookie’ is initialized but never used, which
leads to warning with W=1

drivers/dma/pch_dma.c: In function ‘pd_tx_submit’:
drivers/dma/pch_dma.c:420:15: warning: variable ‘cookie’ set but not used [-Wunused-but-set-variable]
  dma_cookie_t cookie;

So remove it.

This is in preperation of moving to a callback that provides results to the
callback for the transaction. The conversion will maintain current behavior
and the driver must convert to new callback mechanism at a later time in
order to receive results.

Rename the device_control callback of the Intel PCH DMA driver to terminate_all
since it's all it's really doing. That will eventually be used to retrieve
slave capabilities.
