net: nvethernet: Drop adjfreq support

Browse Source 
The 'adjfine' method was first introduced in Linux v4.10 by commit
d8d263541913 ("ptp: Introduce a high resolution frequency adjustment
method.") and the 'adjfreq' method was finally removed in Linux v6.2.
Given that 'adjfine' has been supported since Linux v4.10, drop the
deprecated 'adjfreq' method completely to simplify the nvethernet
driver. This fixes build issues for 3rd party kernels that removed the
'adjfreq' method and are older than Linux v6.2.
