Patch Review

Adds `as_sdp_v2_supported` to `struct intel_dp` and populates it during detect via `intel_dp_detect_sdp_caps()`. The detection logic:
- For eDP: always v2 (per eDP v1.5a)
- For DP: infer from FAVT payload fields parsing or from async video timing not supported in PR

The comment block is thorough. One minor style issue -- double space:
```c
intel_dp->as_sdp_v2_supported = true;
```

Missing R-b.
