RDMA/hns: Add mtr support for mixed multihop addressing

Browse source

Currently, the MTT(memory translate table) design required a buffer
space must has the same hopnum, but the hip08 hw can support mixed
hopnum config in a buffer space.

This patch adds the MTR(memory translate region) design for supporting
mixed multihop.
