From: Xunlei Pang <pang.xunlei@linaro.org>
This driver has a number of y2038/y2106 issues.
This patch resolves them by: - Replace rtc_time_to_tm() with rtc_time64_to_tm() - Replace rtc_tm_to_time() with rtc_tm_to_time64() - Change mxc_rtc_set_mmss() to use rtc_class_ops's set_mmss64()
After this patch, the driver should not have any remaining y2038/y2106 issues.
