dmaengine: mv_xor_v2: new driver
The new mv_xor_v2 driver supports the XOR engines found in the 64-bits ARM from Marvell of the Armada 7K and Armada 8K family. This XOR engine is a completely new hardware block, entirely different from the one used on previous Marvell Armada platforms, which use the existing mv_xor driver.
