sh: sh03: rtc: push down rtc class ops into driver
The SH RTC support has an extra level of indirection to provide either the old read_persistent_clock/update_persistent_clock interface or the rtc-generic device for hctosys/systohc. By removing the indirection and always using the RTC_CLASS interface, we can avoid the lossy double conversion between rtc_time and timespec, so we end up supporting the entire range of 'year' values, and clarifying the rtc_set_time callback. I did not change the behavior of sh03_rtc_settimeofday(), which keeps just updating the seconds/minutes by calling set_rtc_mmss(), this could be improved if anyone cares. Also, the file should ideally be moved into drivers/rtc and not use rtc-generic. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
