Yes, I will change it

The announce of timesync functions are in the #define DRTE_LIBRTE_IEEE1588
While the define of the functions are in the file 'dpaa2_ptp.c'.
So they should be both build or not build by whether the build option -DRTE_LIBRTE_IEEE1588=1 or not.
So it seems not a good idea that remove the conditional.
