kvm: make KVM_COALESCED_MMIO_PAGE_OFFSET public
Its value has never changed; we might as well make it part of the ABI instead of using the return value of KVM_CHECK_EXTENSION(KVM_CAP_COALESCED_MMIO). Because PPC does not always make MMIO available, the code has to be made dependent on CONFIG_KVM_MMIO rather than KVM_COALESCED_MMIO_PAGE_OFFSET.
