You don't need RTC_CLASS for that. All you need is RTC_LIB I think.
What about selecting RTC_LIB from m68k Kconfig just like powerpc and a few architectures do ?
See https://elixir.bootlin.com/linux/v5.18-rc1/source/arch/powerpc/Kconfig#L269
Otherwise, I think it would be better to move (and rename) rtc_tm_to_time64() into kernel/time/time.c instead of opencoding it twice.
