Patch Review

**Author:** Antonios Christidis

Adds `ti,j721e-gpu` with `img,img-ge8430` to the PowerVR Rogue binding.

**Missing blank line:** The diff removes the blank line that separates the BXS-4-64 block from the legacy compatible block comment:

```yaml
-
+      - items:
+          - enum:
+              - ti,j721e-gpu
+          - const: img,img-ge8430
+          - const: img,img-rogue
       # This legacy combination of compatible strings was introduced early on
```

The original blank line before `# This legacy combination` acted as a visual separator. A blank line should be added after the new block to maintain readability:

```yaml
+      - items:
+          - enum:
+              - ti,j721e-gpu
+          - const: img,img-ge8430
+          - const: img,img-rogue
+
       # This legacy combination of compatible strings was introduced early on
```

**The allOf addition looks correct:**

```yaml
              - ti,am62-gpu
              - ti,am62p-gpu
              - ti,j721s2-gpu
+              - ti,j721e-gpu
```

This adds `ti,j721e-gpu` to the list of compatibles that have the single-clock constraint, which is correct.

**Question:** Does the `img,img-ge8430` GPU identifier need any driver-side changes to be recognized? If the driver currently doesn't handle this GPU ID, a driver patch may be needed in this series as well.
