Claude review: drm/exynos/fimd: fix register offset type in fimd_trigger()

Patch Review

**Status: Clean, correct fix.**

The `ctx->regs` field is declared as `void __iomem *regs` (line 182 of `exynos_drm_fimd.c`). When `fimd_trigger()` computes a derived pointer from it:

```c
-	void *timing_base = ctx->regs + driver_data->timing_base;
+	void __iomem *timing_base = ctx->regs + driver_data->timing_base;
```

the old code drops the `__iomem` address space annotation, which causes sparse to rightfully complain when `timing_base` is later passed to `readl()` and `writel()` (lines 1005 and 1007), which expect `__iomem`-qualified pointers.

Adding `__iomem` to the local variable type makes the types consistent throughout the function. This is a no-op change at the binary level (sparse annotations have no runtime effect) but improves static analysis coverage.

The `Fixes:` tag correctly points to commit `3854fab24e89` which introduced the `fimd_trigger()` function with the original type mismatch.

Reviewed-by worthy as-is.
