ptp: convert remaining drivers to adjfine interface

Browse Source 
Convert all remaining drivers that still use .adjfreq to the newer .adjfine
implementation. These drivers are not straightforward, as they use
non-standard methods of programming their hardware. They are all converted
to use scaled_ppm_to_ppb to get the parts per billion value that their
logic depends on.
