[ Upstream commit 341867f730d3d3bb54491ee64e8b1a0c446656e7 ]
The controller is registered using the device-managed function 'devm_mbox_controller_register()'. As documented in mailbox.c, this ensures the devres framework automatically calls mbox_controller_unregister() when device_unregister() is invoked, making the explicit call unnecessary.
Remove redundant mbox_controller_unregister() call as device_unregister() handles controller cleanup.
