ptp: mlx5: convert to .adjfine and adjust_by_scaled_ppm
The mlx5 implementation of .adjfreq is implemented in terms of a
straight forward "base * ppb / 1 billion" calculation.
Convert this to the .adjfine interface and use adjust_by_scaled_ppm for the
calculation of the new mult value.
Note that the mlx5_ptp_adjfreq_real_time function expects input in terms of
ppb, so use the scaled_ppm_to_ppb to convert before passing to this
function.
