Since pages are not pinned anymore we need notifications
when the VMM changes the page-tables. Use mmu_notifiers for
that.
Also use the task_exit notifier from the profiling subsystem
to shutdown all contexts related to this task.

Add a Kconfig option for the optional driver. Since it is
optional it can be compiled as a module and will only be
loaded when required by another driver.
