IB/hfi1: Enable TID RDMA WRITE protocol

This patch enables TID RDMA WRITE protocol by converting a qualified
RDMA WRITE request into a TID RDMA WRITE request internally:
(1) The TID RDMA cability must be enabled;
(2) The request must start on a 4K page boundary;
(3) The request length must be a multiple of 4K and must be larger or
equal to 256K.
