timekeeping: remove timespec_add/timespec_del
The last users were removed a while ago since everyone moved to ktime_t, so we can remove the two unused interfaces for old timespec structures. With those two gone, set_normalized_timespec() is also unused, so remove that as well. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: John Stultz <john.stultz@linaro.org>
