dmaengine: mv_xor: use SoC type instead of directly the operation mode
Currently the main difference between legacy XOR engine and newer one, is the way the engine modes are setup (either in the descriptor or through the controller registers). In order to be able to take into account new generation of the XOR engine for the ARM64 SoC, we need to identify them by type, and then depending to the type the engine setup will be selected.
