cache: ax45mp: Fix device node reference leak in ax45mp_cache_init() 

In ax45mp_cache_init(), of_find_matching_node() returns a device node
with an incremented reference count that must be released with
of_node_put(). The current code fails to call of_node_put() which
causes a reference leak.

Use the __free(device_node) attribute to ensure automatic cleanup when
the variable goes out of scope.
