[PATCH 4/4] x86: rtc: Stop using rtc deprecated functions

[John Stultz]

From: Benjamin Gaignard <benjamin.gaignard@xxxxxxxxxx>

rtc_time_to_tm() and rtc_tm_to_time() are deprecated because they
rely on 32bits variables and that will make rtc break in y2038/2016.
Stop using those two functions to safer 64bits ones.
