    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.
