dmaengine: xilinx_dma: autodetect whether the HW supports scatter-gather
The AXIDMA and CDMA HW can be either direct-access or scatter-gather
version. These are SW incompatible.
The driver can handle both versions: a DT property was used to
tell the driver whether to assume the HW is in scatter-gather mode.
This patch makes the driver to autodetect this information. The DT
property is not required anymore.
No changes for VDMA.
