ls1046a: fsl-fman failure

[Renaud Barbier]

I have recently moved to barebox v2025.06 and the ethernet driver is failing probing.
In the COMMIT below, dev_get_drvdata is replaced by the following function device_get_match_data:

const void *device_get_match_data(struct device *dev)
  {
~         if (dev->of_id_entry) {
+                pr_err("%s A0 return 0x%p\n", __func__, dev->of_id_entry->data);
                  return dev->of_id_entry->data;
+         }

~         if (dev->id_entry) {
+                pr_err("%s A1 return 0x%p\n", __func__, dev->of_id_entry->data);
                  return (void *)dev->id_entry->driver_data;
+         }

+        pr_err("%s return 0x%p\n", __func__, NULL);
          return NULL;
  }

For my specific device, I get the following debug message:
ERROR: fsl-fman-port 1a8b000.port at 8b000.of: probe
ERROR: device_get_match_data A0 return 0x0000000000000000 (here dev->of_id_entry is not NULL  and dev->of_id_entry->data is returned)

and from fsl_fman_port_probe:
ERROR: fsl-fman-port 1a8b000.port at 8b000.of: type = 0. This is a valid type: FMAN_PORT_TYPE_RX = 0
ERROR: fsl-fman-port 1a8b000.port at 8b000.of:  out
