Code in book3s_64_mmu_hv.c, which is in the modular part of HV KVM,
needs to access kvm_hpt_order, which is defined in the built-in part.
Therefore we need to export it.

Alex, it's up to you whether you apply this on your kvm-ppc-next branch
or fold it into the "Make the guest hash table size configurable"
commit - either is fine with me.
