David Gibson f36951c19f pseries: Fix incorrect calculation of RMA size in certain configurations 
For the pseries machine, we need to advertise to the guest the size of its
RMA - that is the amount of memory it can access with the MMU off.  For HV
KVM, this is constrained by the hardware limitations on the virtual RMA of
one hash PTE per PTE group in the hash page table.  We already had code to
calculate this, but it was assuming the VRMA page size was the same as the
(host) backing page size for guest RAM.

In the case of a host kernel configured for 64k base page size, but running
on hardware (or firmware) which only allows 4k pages, the hose will do all
its allocations with a 64k page size, but still use 4k hardware pages for
actual mappings.  Usually that's transparent to things running under the
host, but in the case of the maximum VRMA size it's not.

This patch refines the RMA size calculation to instead use the largest
available hardware page size (as reported by the SMMU_INFO call) which is
less than or equal to the backing page size.  This now gives the correct
RMA size in all cases I've tested.
