Claude review: drm/msm/a8xx: Enable CLX feature on Adreno X2-85

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

Patch Review

**Same `static const` issue as patch 2:**

```c
struct a6xx_hfi_limits_tbl x285_limits_tbl[] = {
```

Should be `static const struct a6xx_hfi_limits_tbl x285_limits_tbl[]`.

**Data is structurally identical to A840 with different tuning values.** The X2-85 has higher current limits (18000 vs 6000 for IFF GX, 66000 vs 30000 for PCLX GX) and different SID values, and both CLX domains have `curr_budget = 100` (vs 100/50 for A840), consistent with a more power-hungry GPU.

**Minor observation:** Patches 2 and 3 place the X2-85 data tables *before* the A840 data tables in the source file (line 1799 vs 2108), which is fine since order doesn't matter for catalog entries, but it does mean the series adds X2-85 tables earlier in the file than A840 tables despite A840 being enabled first in the series. Not a problem, just mildly surprising when reading the diff.

**Summary of requested changes:**

1. **Patch 1**: Make `struct a6xx_limits_tbl::tbl` a `const` pointer: `const struct a6xx_hfi_limits_tbl *tbl`
2. **Patches 2 & 3**: Add `static const` to `a840_limits_tbl[]` and `x285_limits_tbl[]`
