dmaengine: mv_xor: Remove device_control
The Marvell XOR engine doesn't allow any operations that use to be defined in device_control, it shouldn't need to be defined. Since it's going to be deprecated, remove it altogether. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
