This is a refinement of Jan's "[PATCH][4.15] x86/HPET: don't enable legacy
replacement mode unconditionally" to try and make Xen do the helpful thing on
boot, rather than requiring a non-default command line option to boot in the
first place.

  x86/hpet: Factor hpet_enable_legacy_replacement_mode() out of hpet_setup()

  x86/hpet: Don't enable legacy replacement mode unconditionally
