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.
