At the end the carrier offset value for White-Rabbit has been always
constant and it depends on the hardware:
- SVEC: 3000 ps
- SPEC: 0 ps
so, instead of complicate users life by setting this module parameter,
here I am embedding it into the platform_data for the TDC.
The ideal solution would be to ignore this value in software and to
apply it in HDL directly.
