RDMA/ocrdma: Support the new memory registration API
Support the new memory registration API by allocating a
private page list array in ocrdma_mr and populate it when
ocrdma_map_mr_sg is invoked. Also, support IB_WR_REG_MR
by duplicating IB_WR_FAST_REG_MR, but take the needed
information from different places:
- page_size, iova, length, access flags (ib_mr)
- page array (ocrdma_mr)
- key (ib_reg_wr)
The IB_WR_FAST_REG_MR handlers will be removed later when
all the ULPs will be converted.
