Claude review: drm/bridge: analogix_dp: Add support for RK3576

Patch Review

The patch adds `RK3576_EDP` to the `analogix_dp_devtype` enum and makes it fall through to the `RK3588_EDP` case:

```c
+	case RK3576_EDP:
 	case RK3588_EDP:
 		video_info->max_link_rate = 0x14;
 		video_info->max_lane_count = 0x04;
```

This is clean — the cover letter states the eDP TX controller IP is the same as RK3588, so sharing the same max_link_rate (0x14 = HBR2, 5.4 Gbps) and max_lane_count (4) is correct.

The `is_rockchip()` update is also correct:

```c
-	return type == RK3288_DP || type == RK3399_EDP || type == RK3588_EDP;
+	return type == RK3288_DP || type == RK3399_EDP || type == RK3576_EDP || type == RK3588_EDP;
```

**Minor nit:** This function keeps growing with each new SoC. It might be cleaner to use a range check or a default-true approach, but that's a pre-existing issue, not something to block this patch.

No blocking issues.
