[PATCH] remove pps support

This removes the support for pps.  It's completely unused within the kernel
and is basically in the way for further cleanups.  It should be easier to
readd proper support for it after the rest has been converted to NTP4
(where the pps mechanisms are quite different from NTP3 anyway).
