This reverts commit e6d7a3422431868e7538b809cf0d9cc863fa0245.

Reason for revert: CL:5067754 fixes the bug so we can revert this
mitigation and let devices update their TCPCs again.

Original change's description:
> TROGDOR-ONLY: HACK: Skip auxfw sync
>
> In order to allow us to resume system updates on certain Trogdor devices
> that are currently suffering from a bad TCPC update bug which is still
> under investigation, where different users are currently stuck on
> different versions and we are worried that any further update attempts
> with the current code could lead to more bricks, we are completely
> disabling TCPC sync until we have managed to identify the root cause and
> find a proper fix for this issue.
