Claude review: driver core: platform: remove software node on release()

Patch Review

This is the core fix. Adding `device_remove_software_node(dev)` at the top of `platform_device_release()`:

```c
static void platform_device_release(struct device *dev)
{
    struct platform_object *pa = container_of(dev, struct platform_object,
                          pdev.dev);

    device_remove_software_node(dev);
    of_node_put(pa->pdev.dev.of_node);
    ...
```

This correctly handles the case where a swnode was added via `device_add_software_node()` (the `.swnode` path). For managed swnodes (`.properties` path), `device_remove_software_node()` is a no-op because `software_node_notify_remove()` already cleared the secondary fwnode during `device_del()`.

The extra `fwnode_handle_get()` for the primary-fwnode-is-software-node case is correct:

```c
if (is_software_node(pdevinfo->fwnode))
    fwnode_handle_get(pdevinfo->fwnode);
```

This prevents the new `device_remove_software_node()` in release from dropping the refcount of a pre-existing software node that was passed as the primary fwnode — the caller owns that node's lifetime.

The commit message could be slightly clearer: "it will fails" should be "it will fail".

No functional issues.
