952061352a drivers: rtc: correctly convert seconds to time structure 
Variable 'days' must be defined as signed int. Otherwise the conversion
fails for some dates, e.g. 2004-08-25. Cf function rtc_time64_to_tm() in
the Linux kernel source.

992c1db455 drivers: rtc: resolve year 2038 problem in rtc_to_tm 
Our implementation of rtc_to_tm() cannot handle dates of more than
0x7fffffff seconds after 1970-01-01.

Adopt the Linux kernel implementation.
