dmaengine: mv_xor_v2: use {lower,upper}_32_bits to configure HW descriptor address
>> drivers/dma/mv_xor_v2.c:647:36: sparse: constant 0xFFFF00000000 is so big it is long
include/linux/device.h:678:13: sparse: undefined identifier '__builtin_mul_overflow'
include/linux/device.h:678:13: sparse: call with no type!
Use lower_32_bits and upper_32_bits to set the hw_desq address, instead of
using constant.
