Claude review: drm/exynos: exynos_dp: Apply of-display-mode-bridge to parse the display-timings node

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

**Summary:** Uses the new generic of-display-mode-bridge instead of custom parsing logic.

**Before:**
```c
-static int exynos_dp_get_modes(struct analogix_dp_plat_data *plat_data,
-			       struct drm_connector *connector)
-{
-	struct exynos_dp_device *dp = to_dp(plat_data);
-	struct drm_display_mode *mode;
-
-	mode = drm_mode_create(connector->dev);
-	if (!mode) {
-		DRM_DEV_ERROR(dp->dev,
-			      "failed to create a new display mode.\n");
-		return 0;
-	}
-
-	drm_display_mode_from_videomode(&dp->vm, mode);
```

**After:**
```c
+	ret = drm_of_find_panel_or_bridge(dev->of_node, 0, 0, &panel, &bridge);
+	if (ret == -ENODEV) {
+		dp->plat_data.next_bridge = devm_drm_of_display_mode_bridge(dp->dev,
+									dp->dev->of_node,
+									DRM_MODE_CONNECTOR_eDP);
```

**Review:**
- Removes 27 lines of custom code in favor of generic helper
- The `has_of_bridge` flag is temporary (mentioned in commit message) - acceptable for staged refactoring
- Error handling is preserved

**Concern:** The temporary flag creates technical debt, but patch 9 should remove it.

**Verdict:** Good refactoring, verify flag removal in later patches.
