This driver uses mktime() and rtc_time_to_tm() to convert between time values. This works fine on 64-bit kernels over the whole supported range, and the vr41xx chip is a 64-bit MIPS implementation, but it is inconsistent because it doesn't do the same thing on 32-bit kernels that overflow in 2106 or 2038.
Changing it to use mktime64/rtc_time64_to_tm() should have no visible impact on vr41xx but gets us closer to removing the 32-bit interfaces.

I've applied the series a while ago. It should be noted that mktime64 will fail on 32bit platforms in year 21000 or so but I pretty sure it is not worth fixing. My understanding is that the kernel will fail in April 2262 anyway as ktime_t will overflow.
Note that I will be following up with multiple series adding proper rtc HW range, removing set_mmss and rtc_time_to_tm/rtc_tm_to_time64.
