net/mlx5: Add firmware support for MTUTC scaled_ppm frequency adjustments
When device is capable of handling scaled ppm values for adjusting
frequency, conversion to ppb will not be done by the driver. Instead, the
scaled ppm value will be passed directly to the device for the frequency
adjustment operation.
