Claude review: drm/fsl-dcu: Open-code drm_simple_encoder_init()

Patch Review

**Correctness: OK**

The transformation is correct. The new struct:
```c
static const struct drm_encoder_funcs fsl_dcu_drm_encoder_funcs = {
	.destroy = drm_encoder_cleanup,
};
```
is placed at file scope before its first use in `fsl_dcu_drm_encoder_create()`, and the call is correctly changed from:
```c
drm_simple_encoder_init(fsl_dev->drm, encoder, DRM_MODE_ENCODER_LVDS);
```
to:
```c
drm_encoder_init(fsl_dev->drm, encoder, &fsl_dcu_drm_encoder_funcs,
                 DRM_MODE_ENCODER_LVDS, NULL);
```

The `NULL` name argument matches what `drm_simple_encoder_init()` passed. The include removal is safe since no other symbols from `drm_simple_kms_helper.h` are used.

Reviewed-by worthy.
