Akinobu Mita 676f9c26c3 dmaengine: xilinx: fix device_terminate_all() callback for AXI CDMA 
The device_terminate_all() callback for this driver stops current DMA
operations by clearing RUNSTOP bit in the control register and waiting
HALTED bit set in the status register.

But AXI CDMA which is one of the supported DMA engine by this driver
does not provide the run / stop controls and those bits in the control
and status registers are reserved.  So when device_terminate_all() is
called, the error message is printed and the channel is marked as having
errors in xilinx_dma_halt().

This change adds stop_transfer() callback which differentiates CDMA and
other DMA engine.  The CDMA's one avoids the unsupported operations and
instead polls the status register to check if the DMA operations are in
progress for AXI CDMA.
