Subject: [PATCH] powerpc: xmon: use ktime_get_coarse_boottime64
get_monotonic_boottime() is deprecated, and may not be safe to call in
every context, as it has to read a hardware clocksource.
This changes xmon to print the time using ktime_get_coarse_boottime64()
instead, which avoids the old timespec type and the HW access.
