Benjamin Gray e410dfaaac powerpc/watchpoints: Annotate atomic context in more places 
[ Upstream commit 27646b2e02b096a6936b3e3b6ba334ae20763eab ]

It can be easy to miss that the notifier mechanism invokes the callbacks
in an atomic context, so add some comments to that effect on the two
handlers we register here.
