rtc: pcf8563: Replace deprecated rtc_time_to_tm() and rtc_tm_to_time()
pcf8563_rtc_set_alarm() uses deprecated rtc_tm_to_time()
and rtc_time_to_tm(), which will overflow in year 2106
on 32-bit machines.
This patch solves this by:
- Replacing rtc_time_to_tm() with rtc_time64_to_tm()
- Replacing rtc_tm_to_time() with rtc_tm_to_time64()
