powerpc fixes for 4.15 #8

More than we'd like after rc8, but nothing very alarming either, just tying up
loose ends before the release:

Since we changed powernv to use cpufreq_get() from show_cpuinfo(), we see
warnings with PREEMPT enabled. But the preempt_disable() in show_cpuinfo()
doesn't actually prevent CPU hotplug as it suggests, so remove it.

Two updates to the recently merged RFI flush code. Wire up the generic sysfs
file to report the status, and add a debugfs file to allow enabling/disabling it
at runtime.

Two updates to xmon, one to add the RFI flush related fields to the paca dump,
and another to not use hashed pointers in the paca dump.

And one minor fix to add a missing include of linux/types.h in asm/hvcall.h, not
seen to break the build in upstream, but correct anyway.

Thanks to:
  Benjamin Herrenschmidt, Michal Suchanek, Nicholas Piggin.
