Hi,

These are set of small fixes around FF-A notification support that are
currently queued in -next. It is mostly to take care of absence of
the notification support in the firmware as well as allowing them to be
optional and continue initialisation even when the notification fails.

Regards,
Sudeep

Works as expected with and without FF-A notifications enabled in the
secure world.
