[PATCH V2 1/4] mailbox: zynqmp-ipi: Remove redundant mbox_controller_unregister() call

[Harini T <harini.t@amd.com>]

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.
