Claude review: drm/amd/display: Wrap dcn32_override_min_req_memclk() in DC_FP_{START, END}

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

Patch Review

**Correctness: Correct.**

The added guards:
```c
DC_FP_START();
dcn32_override_min_req_memclk(dc, context);
DC_FP_END();
```

are necessary because `dcn32_override_min_req_memclk()` is defined in `dcn32_fpu.c` (confirmed at `dcn32_fpu.c:3600`), which is compiled with `CC_FLAGS_FPU` per `dc/dml/Makefile:28,65`. The sibling function `dcn32_override_min_req_dcfclk()` at line 1792 does **not** need wrapping because it lives in `dcn32_resource_helpers.c` (a non-FPU file), which is correct.

**Observations:**

1. The commit message is clear and well-structured with the `[Why]` format used by the amdgpu display team.
2. The `Fixes:` tag correctly references `ee7be8f3de1c` which introduced the unguarded call.
3. The `Cc: stable@vger.kernel.org` is appropriate for a bug fix that causes real failures on LoongArch hardware.
4. The pattern is consistent with how `dcn32_internal_validate_bw()` is already wrapped at lines 1770-1771 in the same function.

**No issues found.**
