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.
