Revert "mb/starlabs/*:	Enable the Mirror flag for boards that support"

This reverts commit 35354583cdc94ced026975ced5170e1c094b258e.

Reason for revert: The mirror flag "0x01" is mirror once, which
relies on the EC remembering that it's been mirrored. However, the
EC forgets this if it's been without power for 20 minutes or so.

Even if power is connected then, it'll instantly try to mirror and
it can't charge whilst doing it. It can either result in
incomplete EC firmware, or a loop where it's constantly trying to
mirror.
