Patch Review

Fixes the bit-shift bug in `intel_dp_as_sdp_unpack()`:
```c
- as_sdp->target_rr = (u64)sdp->db[3] | ((u64)sdp->db[4] & 0x3);
+ as_sdp->target_rr = ((sdp->db[4] & 0x3) << 8) | sdp->db[3];
```
The old code OR'd DB[4] bits 1:0 into bits 1:0 of the result, overwriting DB[3] bits. Correct fix. Has Ville's R-b. Should have `Cc: stable`.
