media: ti: vpe: Fix fwnode_handle leak in vip_probe_complete()

In vip_probe_complete(), the fwnode_handle reference is not released
if the loop continues via the default switch case or if alloc_port()
fails. This results in a reference count leak.

Switch to using the __free(fwnode_handle) cleanup attribute to ensure
the reference is automatically released when the handle goes out of
scope.
