dmaengine: dw-edma: Join read/write channels into a single device
There is no point in splitting read/write channels. First of all, eDMA
read and write channels belong to one physical controller. Secondly,
channel differentiation can be done by filtering and dma_get_slave_caps().
Finally, having these channels handled separately needlessly complicates
the code and causes this debugfs warning:
debugfs: Directory '1f052000.pcie' with parent 'dmaengine' already present!
Join the read/write channels into a single DMA device. Client drivers can
choose the correct channel via the DMA slave direction setting. The default
value is overridden by the dw_edma_device_caps() callback in accordance
with the channel type.
