[PATCH 2/3] KVM: arm64: Declare support for KVM_CAP_MEMORY_FAULT_INFO

[Anish Moorthy <amoorthy@google.com>]

Although arm64 doesn't currently use memory fault exits anywhere,
it's still valid to advertise the capability: and a subsequent commit
will add KVM_EXIT_MEMORY_FAULTs to the stage-2 fault handler
