sb/intel/common/firmware: Enable me_cleaner for Nehalem
Recent patches in coreboot have fixed the freeze issues related to the
use of me_cleaner on Nehalem.
However, at least on the Lenovo X201, with me_cleaner some PCIe devices
(like the SATA and USB controllers) disappear. In particular, setting
the AltMeDisable bit ("-S" or "-s" flag) makes them disappear
completely, while unsetting it makes them disappear only during cold
boots.
This kind of behaviour was already observed by Youness Alaoui on the
Purism Librem laptops ([1]), and it seems related to some required
board-specific PCIe configuration in the ME's MFS partition.
For this reason, on the Lenovo X201, "-w EFFS" has been added to the
me_cleaner arguments, which whitelists the MFS-equivalent partition for
ME generation 2. This fixes all the issues, and the PCIe devices work as
expected.
