drivers/rtc/mxc: Update driver to address y2038/y2106 issues
This driver has a number of y2038/y2106 issues.
This patch resolves them by:
- Replacing rtc_time_to_tm() with rtc_time64_to_tm()
- Replacing rtc_tm_to_time() with rtc_tm_to_time64()
- Changing 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.
