net/mlx5: DPLL, fix fractional frequency offset scaling
The frequency_diff is reported by firmware in parts-per-trillion, which
is exactly what the DPLL core now expects from the ffo_get callback.
Commit bc443c253fcd ("dpll: expose fractional frequency offset in ppt")
switched the callback contract to ppt but assumed frequency_diff was in
ppm and scaled it by 1000000 to "convert" it. Since the value was
already ppt, this makes both exported attributes wrong.
Report frequency_diff as is and let the core divide it down for the
legacy ppm attribute.
Fixes: f035dca34ede ("net/mlx5: DPLL, Implement fractional frequency offset get pin op")
