mb/hp/snb_ivb_laptops: Switch to overridetree setup

NOTE: The ME interface was disabled on folio_9470m and revolve_810_g1.
It is assumed that they were ported while the ME was in an abnormal
state (usually due to me_cleaner usage), and that it should be enabled.
In any case, the MEI device is hidden if the ME fails to boot already.
