ptp: tg3: convert .adjfreq to .adjfine

Browse source

The tg3 implementation of .adjfreq is implemented in terms of a
straight forward "base * ppb / 1 billion" calculation.

Convert this to the newer .adjfine, using the recently added
diff_by_scaled_ppm helper function to calculate the difference and
direction of the adjustment.
