mlx4_core: Support ICM tables in coherent memory
Enable having ICM tables in coherent memory, and use coherent memory for the dMPT table. This will allow writing MPT entries for MRs both via the SW2HW_MPT command and also directly by the driver for FMR remapping without needing to flush or worry about cacheline boundaries.
