Whenever a single or cyclic transaction is prepared, the driver
could eventually split it over several SG descriptors in order
to deal with the HW maximum transfer length.
This could end up in DMA operations starting from a misaligned

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. T
