sh: remove unused rtc_sh_get/set_time infrastructure
All platforms are now converted to RTC drivers, so this has become obsolete. The board_time_init() callback still has one caller, but could otherwise also get killed. This removes one more usage of the deprecated timespec structure, which overflows in y2038. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
