Implement parsing for timer_mode, hpet and vpt_align parameters. These are all HVM only parameters and hpet/vpt_align are boolean so change types and place in hvm union accordingly. Also HPET is x86 only on principle so make this compile-time conditional on arch as-is viridian. Signed-off-by: Gianni Tedesco <gianni.tedesco@citrix.com>
