drivers: Intel: hda-dma: only check DGCS_BUSY with delayed stop When an older kernel is used, we use the immediate stop. On some platforms, we see an -EBUSY error that prevents the trigger stop from working. This patch adds a check to be 'bug-compatible' with previous releases and older kernels. An additional fix would be to insert a poll timeout to make sure the BUSY bit is cleared.
