net/mlx5: Add adjphase function to support hardware-only offset control

Browse source

The adjtime function supports using hardware to set the clock offset when
the delta was supported by the hardware. When the delta is not supported by
the hardware, the driver handles adjusting the clock. The newly-introduced
adjphase function is similar to the adjtime function, except it guarantees
that a provided clock offset will be used directly by the hardware to
adjust the PTP clock. When the range is not acceptable by the hardware, an
error is returned.
