timekeeping: Store cycle_last value in timekeeper struct as well
...
For implementing a shadow timekeeper and a split calculation/update
region we need to store the cycle_last value in the timekeeper and
update the value in the clocksource struct only in the update region.
Add the extra storage to the timekeeper.

timekeeping: Move TAI managment into timekeeping core from ntp
...
Currently NTP manages the TAI offset. Since there's plans for a
CLOCK_TAI clockid, push the TAI management into the timekeeping
core.

We're going to need to access the timekeeper in update_vsyscall,
so make the structure available for those who need it.
