The domain flag SD_PREFER_SIBLING was set both on MC and CPU domain at frist commit b5d978e0c7e79a, and was removed uncarefully when clear up obsolete power scheduler. Then commit 6956dc568 recover the flag on CPU domain only. It works, but it introduces a extra domain level since this cause MC/CPU different.
So, recover the the flag in MC domain too to remove a domain level in x86 platform.
