Claude review: drm/msm/dp: introduce stream_id for each DP panel

Patch Review

**Unnecessary NULL check after container_of()**:
```c
+ dp = container_of(msm_dp_display, struct msm_dp_display_private, msm_dp_display);
+
+ if (!dp) {
+ DRM_ERROR("invalid input\n");
+ return -EINVAL;
+ }
```
`container_of()` performs pointer arithmetic — it will never return NULL (unless the input itself is NULL, which would make the container_of result non-NULL anyway, just a garbage pointer). This check is dead code and should be removed.
