    There is still a config option for hpet. the hpet=force boot param is
    there to allow force enable hpet for not documented chip set features.

    It's not necessary to scan in early_quirks.c at all. The force hpet
    code handles the late DECLARE_PCI_FIXUP_HEADER() based detection just

    So if there are working quirks, please refactor them analogous to the
    existing ones in quirks.c.

    All undocumented chipset poking needs to be protected by the
    hpet=force boot option, so the default is not to do scan for it.
