We have currently three users of the PSEC_PER_SEC each of them defining it
individually. Instead, move it to time64.h to be available for everyone.

There is a new user coming with the same constant in use. It will also
make its life easier.

v2: added tag (Heiko), rebased on top of newest rc

Since it touches PHY stuff, I assume that the PHY tree is the best
to suck this.
