device property: Add cleanup.h based fwnode_handle_put() scope based cleanup.

JIRA: https://issues.redhat.com/browse/RHEL-66957
CVE: CVE-2024-50197

commit 59ed5e2

    device property: Add cleanup.h based fwnode_handle_put() scope based cleanup.

    Useful where the fwnode_handle was obtained from a call such as
    fwnode_find_reference() as it will safely do nothing if IS_ERR() is true
    and will automatically release the reference on the variable leaving
    scope.
