Author: Sepherosa Ziehau <sephe@dragonflybsd.org>

    Allow one shot timer to be switched on a running system between i8254 and
    lapic timer:
    
    - Always register "clk" interrupt.
    - Add cputimer_intr_switch(), which could switch one shot timer between
      i8254 and lapic timer on a running system.  It could be used to select
      a proper one shot timer duing ACPI C3 transition:
      e.g. ->C3 use i8254, C3-> use lapic timer
    - Add sysctl node hw.cputimer_intr_type to test cputimer_intr_switch().
