char: ipmi: ipmi_ssif: Replace timeval with timespec64



This patch replaces timeval with timespec64 as 32 bit 'struct timeval'
will not give current time beyond 2038.

The patch changes the code to use ktime_get_real_ts64() which returns
a 'struct timespec64' instead of do_gettimeofday() which returns a
'struct timeval'

This patch also alters the format string in pr_info() for now.tv_sec
to incorporate 'long long' on 32 bit architectures.
