mailbox: zynqmp-ipi: Remove redundant mbox_controller_unregister() call

Browse source 
[ 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.
