David Gibson e8b1144e73 spapr, ppc: Remove VPM0/RMLS hacks for POWER9 
For the "pseries" machine, we use "virtual hypervisor" mode where we
only model the CPU in non-hypervisor privileged mode.  This means that
we need guest physical addresses within the modelled cpu to be treated
as absolute physical addresses.

We used to do that by clearing LPCR[VPM0] and setting LPCR[RMLS] to a high
limit so that the old offset based translation for guest mode applied,
which does what we need.  However, POWER9 has removed support for that
translation mode, which meant we had some ugly hacks to keep it working.

We now explicitly handle this sort of translation for virtual hypervisor
mode, so the hacks aren't necessary.  We don't need to set VPM0 and RMLS
from the machine type code - they're now ignored in vhyp mode.  On the cpu
side we don't need to allow LPCR[RMLS] to be set on POWER9 in vhyp mode -
that was only there to allow the hack on the machine side.
