Log message:
acpitimer(4): add acpitimer_delay(), another delay(9) implementation
When lapic_delay() is removed from the tree in the near future, older
machines without a constant/invariant TSC will need a delay(9)
implementation better than i8254_delay().
This patch adds acpitimer_delay(), a delay(9) implementation based on
the ACPI PM timer. It is only preferable to i8254_delay(), so set its
quality to 1000.
With input from jsg@.
