timekeeping: Remove unused timekeeping_{get,set}_tai_offset()
The last caller to timekeeping_set_tai_offset() was in commit0b5154fb90
(timekeeping: Simplify tai updating from do_adjtimex, 2013-03-22) and the last caller to timekeeping_get_tai_offset() was in commit76f4108892
(hrtimer: Cleanup hrtimer accessors to the timekepeing state, 2014-07-16). Remove these unused functions now that we handle TAI offsets differently. Cc: John Stultz <john.stultz@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: John Stultz <john.stultz@linaro.org>
