[regression] mei: me: allow runtime pm for platform with D0i3

[Jeremy Cline]

Hi folks,

Fedora has received a number of reports of e1000e-driven ethernet ports
negotiating 10Mbps links if the cable is disconnected and reconnected
after boot on a number of laptops, including the Lenovo T480s[0].

Kamil git-bisected the issue to commit cc365dcf0e56 ("mei: me: allow
runtime pm for platform with D0i3") and has confirmed that reverting
that commit in v4.20 fixes the issue.
