net/mlx5: Add hardware extended range support for PTP adjtime and adjphase

Browse source

Capable hardware can use an extended range for offsetting the clock. An
extended range of [-200000,200000] is used instead of [-32768,32767] for
the delta/phase parameter of the adjtime/adjphase ptp_clock_info callbacks.
