[RFC v7 24/26] hw/arm/smmuv3: Allow MAP notifiers


From: Eric Auger
Subject: [RFC v7 24/26] hw/arm/smmuv3: Allow MAP notifiers
Date: Mon, 16 Nov 2020 19:13:47 +0100

We now have all bricks to support nested paging. This
uses MAP notifiers to map the MSIs. So let's allow MAP
notifiers to be registered.
