Claude review: drm: renesas: rz-du: mipi-dsi: drop duplicate platform_set_drvdata() call

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

Patch Review

**Correctness: OK**

Confirmed in the source tree that there are indeed two identical calls:
- Line 1405: `platform_set_drvdata(pdev, dsi);` (right after `devm_drm_bridge_alloc`)
- Line 1444: `platform_set_drvdata(pdev, dsi);` (after reset controller acquisition)

The `dsi` pointer is not reassigned between the two calls, and no runtime callbacks that read driver data can fire before probe returns, so removing either call is safe. The v2 decision to drop the *first* occurrence (line 1405) rather than the second is fine — it keeps the call closer to the `pm_runtime_enable()` at line 1446, which is the first point where PM callbacks could theoretically be invoked.

**Nit (commit message):** "occurence" in the v2 changelog should be "occurrence", but this is below the `---` line so it won't be in the git history.

**No functional concerns.** This is a clean one-line removal with no behavioral impact.
