powerpc/powernv: Require MMU_NOTIFIER to fix NPU build

In the recent commit 1ab66d1 ("powerpc/powernv: Introduce address translation services for Nvlink2") the NPU code gained a dependency on MMU notifiers. All our defconfigs have KVM enabled, which selects MMU_NOTIFIER, but if KVM is not enabled then the build breaks. Fix it by always selecting MMU_NOTIFIER when we're building powernv.
