e1000e: Remove Meteor Lake SMBUS workarounds

This is a partial revert to commit 76a0a3f9cc2f ("e1000e: fix force smbus
during suspend flow"). That commit fixed a sporadic PHY access issue but
introduced a regression in runtime suspend flows.
The original issue on Meteor Lake systems was rare in terms of the
reproduction rate and the number of the systems affected.

After the integration of commit 0a6ad4d9e169 ("e1000e: avoid failing the
system during pm_suspend"), PHY access loss can no longer cause a
system-level suspend failure. As it only occurs when the LAN cable is
disconnected, and is recovered during system resume flow. Therefore, its
functional impact is low, and the priority is given to stabilizing
runtime suspend.
