dmaengine: ti: edma: support sw triggered chans in of_edma_xlate()

The .of_edma_xlate() function always sets the hw_triggered flag to
true. This causes sw triggered channels consumed via the device-tree
to not function properly, as the driver incorrectly assumes they are
hw triggered. Modify the xlate() function to correctly set the
hw_triggered flag to false for channels reserved for memcpy
operation (ie, sw triggered).
