sb/intel/common: Hook up me_cleaner
The me_cleaner option is available on multiple platforms:
* Sandy and Ivy Bridge (well tested by multiple users).
* Skylake and Braswell (tested).
* Haswell, Broadwell and Bay Trail (untested).
The untested platforms have been included anyways because all the
firmwares are very similar and Intel ME/TXE probably behaves in the
same way.
