With s390's switch to MMU notifier, all architectures select
CONFIG_KVM_GENERIC_MMU_NOTIFIER and define KVM_CAP_SYNC_MMU,
so remove the possibility to _not_ have them.

The only intricate Kconfig-ery is powerpc's, but there is
a nice pre-existing BUILD_BUG_ON to tell us that it *does*
in fact require CONFIG_KVM_GENERIC_MMU_NOTIFIER.

v1->v2: do select MMU_NOTIFIER

Paolo Bonzini (2):
  KVM: remove CONFIG_KVM_GENERIC_MMU_NOTIFIER
  KVM: always define KVM_CAP_SYNC_MMU
