timekeeping: remove unused {read,update}_persistent_clock
After arch/sh has removed the last reference to these functions, we can remove them completely and just rely on the 64-bit time_t based versions. This cleans up a rather ugly use of __weak functions. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: John Stultz <john.stultz@linaro.org>
