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.
