There seems to be lot of confusion here. Current code isn't using hpet
as tick source if legacy is not supported. This patch adds
hpet_lrr_force but it's not clear how it interacts with hpet_use_timer -
in some places it is hpet_use_timer and some (hpet_use_timer &&
hpet_lrr_force).

The timer is routed to ioapic pin 2 which is irq0 with source override.
With this patch with hpet_lrr_force=1 timer irq is set to 2 for x86_64
and 0 for i386, that can't be right?
Hmm... if hpet_lrr_force=1, timer irq should be set to 2 both in
x86_64 as well as i386.
This is my mistake. I should test more thoroughly :-(

Thanks for comments.
Om.
