  firmware: arm_ffa: Fix ffa_notification_info_get() IDs handling (2023-11-13 11:51:26 +0000)

----------------------------------------------------------------
Arm FF-A fixes for v6.7

A bunch of fixes addressing issues around the notification support that
was added this cycle. They address issue in partition IDs handling in
ffa_notification_info_get(), notifications cleanup path and the size of
the allocation in ffa_partitions_cleanup().

It also adds check for the notification enabled state so that the drivers
registering the callbacks can be rejected if not enabled/supported.

It also moves the partitions setup operation after the notification
initialisation so that the driver has the correct state for notification
enabled/supported before the partitions are initialised/setup.

It also now allows FF-A initialisation to complete successfully even
when the notification initialisation fails as it is an optional support
in the specification. Initial support just allowed it only if the
firmware didn't support notifications.

Finally, it also adds a fix for smatch warning by declaring ffa_bus_type
structure in the header.
