Renames xilinx_vdma_ prefix to xilinx_dma which includes renaming of
the above properties.

That patch changes driver from vdma to dma. It does not change property
name!

The patch (dmaengine: vdma: Rename xilinx_vdma_ prefix to
xilinx_dma) already got applied in the dma-next tree.
That's why sent this patch to sync with the current driver I mean
latest driver.

The correct solution for this is to revert that part of the change
ASAP,
since, as Soeren pointed out, it breaks all existing users.

No the commit applied is only the name changes inside the driver. They
don't break anything yet. IIUC this patch breaks not the applied one..

Thanks
