Subject: mei: me: set internal pg flag to off on hardware reset
Git-commit: 9f4639373e6756e1ccf0029f861f1061db3c3616
Patch-mainline: v5.19-rc3
References: jsc#PED-1218

Link reset flow is always performed in the runtime resumed state.
The internal PG state may be left as ON after the suspend
and will not be updated upon the resume if the D0i3 is not supported.

Ensure that the internal PG state is set to the right value on the flow
entrance in case the firmware does not support D0i3.
