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.
Paolo
v1->v2: do select MMU_NOTIFIER

KVM: remove CONFIG_KVM_GENERIC_MMU_NOTIFIER
KVM: always define KVM_CAP_SYNC_MMU

All architectures now use MMU notifier for KVM page table management.
Remove the Kconfig symbol and the code that is used when it is
disabled.

KVM_CAP_SYNC_MMU is provided by KVM's MMU notifiers, which are now always
available. Move the definition from individual architectures to common
code.
