Dotcase: Improve handling of notifications

Handle and draw notifications in the order they are returned by the
INotificationManager (i.e., the order they were posted). This new
handling is also easier to extend with new apps (for existing sprites)
and new sprites altogether.

Also, if there are more than 6 notifications to draw, only draw the
first 5 and add a "..." sprite at the end. Now that we have a way to
handle more than 6 notifications, we can add more types of
notifications.

PS2: Use a Map instead of a bunch of Sets to map package names to
notification types

m8: Keep two cores online

 * The recommended behavior for 8974pro is to keep two cores online
   at all times, as all cores can enter full power collapse at any
   time. Recently, we upgraded the perf lib which controlled this,
   and this new property is required to achieve the behavior we want.
