Subject: [PATCH 2/3] rtc: sun4v: set range

The Sun4v Hypervisor Core API Specification states:
Time is described by a single unsigned 64-bit word equivalent to a time_t
for the POSIX time(2) system call. The word contains the time since the
Epoch (00:00:00 UTC, January 1, 1970), measured in seconds.
