[PATCH 4/9][U/OEM-5.10] Revert "UBUNTU: SAUCE: e1000e: Add Dell's Comet Lake systems into s0ix heuristics"

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1910541

This reverts commit 5fa550a99a4e2c9c894a64da4dbc8510ee7c9c5c.

Formally enable s0ix for all platform, then we can remove quirks that
enable s0ix on the specific platform.
