x86: enable HPET on Fujitsu u9200
Impact: auto-enable HPET on Fujitsu u9200
HPET timer is listed in the ACPI table, but needs a quirk entry in order to
work. Unfortunately, the quirk code runs after first HPET hpet_enable() which
has already determined that the timer doesn't work (reads 0xFFFFFFFF). This
patch allows hpet_enable() to be called again after running the quirk code.
