Patch Review

Wraps the drm core function with a `DISPLAY_VER(display) < 35` guard.

**Kdoc mismatch:**
```
* Returns %true if the BW allocation mode is supported on @intel_dp.
```
This is copy-pasted from the BW allocation function — it should say "PR BW optimization" instead of "BW allocation mode". The function name and description mention PR optimization correctly, but the Returns line is wrong.

**DISPLAY_VER check:** Gating on display version >= 35 is reasonable as this is a new platform feature. The stub for `CONFIG_DRM_DISPLAY_DP_TUNNEL=n` is correct.
