[PATCH 1/4] UBUNTU: SAUCE: e1000e: fix S0ix flow to allow S0i3.2 subset entry

[Timo Aaltonen]

From: Vitaly Lifshits <vitaly.lifshits at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1902687

Changed a configuration in the flows to align with
architecture requirements to achieve S0i3.2 substate.

Also fixed a typo in the previous patch- e1000e: fix S0ix flows for
cable connected case (632fbd5eb5b).
