drivers/rtc: Provide y2038 safe rtc_class_ops.set_mmss() replacement
Currently the rtc_class_op's set_mmss() function takes a 32-bit
second value (on 32-bit systems), which is problematic for dates
past y2038.
This patch provides a safe version named set_mmss64() using
y2038 safe time64_t.
After this patch, set_mmss() is deprecated and all its users
will be fixed to use set_mmss64(), it can be removed when having
no users.
