ntp: Move do_adjtimex() and hardpps() functions to timekeeping.c In preparation for changing the ntp locking rules, move do_adjtimex and hardpps accessor functions to timekeeping.c, but keep the code logic in ntp.c. This patch also introduces a ntp_internal.h file so timekeeping specific interfaces of ntp.c can be more limitedly shared with timekeeping.c.

ntp: Move timex validation to timekeeping do_adjtimex call. Move logic that does not need the ntp state to be done in the timekeeping do_adjtimex() call.

ntp: Rework do_adjtimex to take timespec and tai arguments In order to change the locking rules, we need to provide the timespec and tai values rather then having the ntp logic acquire these values itself.
