Time-sensitive networking code needs to work with PTP times expressed in nanoseconds, and with packet transmission times expressed in picoseconds, since those would be fractional at higher than gigabit speed when expressed in nanoseconds. Convert the existing uses in tc-taprio and the ocelot/felix DSA driver to a PSEC_PER_NSEC macro. This macro is placed in include/linux/time64.h as opposed to its relatives (PSEC_PER_SEC etc) from include/vdso/time64.h because the vDSO library does not (yet) need/use it.
