Hello Alexander Couzens, Patrick Rudolph,

I'd like you to reexamine a change. Please visit

mb/lenovo: Enable MEI on Sandy Bridge ThinkPads

It was already enabled on T520 and L520, but disabled on X220, T420 and
T420s.

On X220, it was disabled by 0793afe9. I can't reproduce those issues
today.

Also:
- it breaks the me_disable feature,
- we already have a Kconfig option to hide MEI in case of errors,
- it will be hidden on disabled, recovery, firmware update paths anyway.
