net/mlx5: Add register layout to support real-time time-stamp
Add needed structure layouts and defines for MTUTC (Management UTC)
register. MTUTC will be used for cyc2time HW translation.
In addition, add cyc2time modify capability bit and init segment HCA
real time address.
Finally, add capability bits indicating which time-stamping format is
supported per SQ and RQ. Add ts_format in the queue's context layout to
allow configuration.
