From: Hanna Hawa <hannah@xxxxxxxxxxx> Remove unnecessary write to DESQ_STOP register, this register is used to enable or disable the XOR engine, and not to issue all pending descriptors in the queue. mv_xor_v2 driver already writes to this register and enable XOR engine in the mv_xor_v2_descq_init() function, called during initialization.
