Patch Review

The function signature change adds a `bool is_pr_with_link_off` parameter. The condition:
```c
+ link_config[0] |= is_pr_with_link_off ? DP_FIXED_VTOTAL_AS_SDP_EN_IN_PR_ACTIVE : 0;
```
This sets bit 6 of DPCD 0x107 when Panel Replay with link-off is active, which matches the spec definition. The call site passes `intel_alpm_is_alpm_aux_less(intel_dp, crtc_state)` which is correct.

The MST caller passes `false` for the new parameter — correct since MST doesn't use PR with link-off. No R-b tag.
