[MIPS] Switch from to_tm to rtc_time_to_tm
This replaces the MIPS-specific to_tm function with the generic rtc_time_to_tm function. The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
