mlx4_core: Write MTTs from CPU instead with of WRITE_MTT FW command
Write MTT entries directly to ICM from the driver (eliminating use of
WRITE_MTT command). This reduces the number of FW commands needed to
register an MR by at least a factor of 2 and speeds up memory
registration significantly. This code will also be used to implement
FMRs.
