Patch Review

**Issue: The DPCD address 0x11a for `PANEL_REPLAY_CONFIG3` doesn't look right.** The existing `PANEL_REPLAY_CONFIG` is at 0x1b0 and `PANEL_REPLAY_CONFIG2` is at 0x1b1. Address 0x11a is in a different DPCD region entirely (near the payload allocation area at 0x1c0). Patch 15 then does a 3-byte burst write starting at `PANEL_REPLAY_CONFIG` (0x1b0), which would write to 0x1b0, 0x1b1, and 0x1b2 — not 0x11a. Either:
- The address 0x11a is wrong and should be 0x1b2, or
- The burst write in patch 15 is wrong

This needs clarification against the DP 2.1 spec. No R-b tag on this patch.

```c
+#define PANEL_REPLAY_CONFIG3 0x11a /* DP 2.1 */
```
