markj 2478632638 Defer ACPI taskqueue creation to SI_SUB_KICK_SCHEDULER.
This addresses a deadlock during boot when EARLY_AP_STARTUP is configured:
a taskqueue thread may call pause() with an ACPI mutex held, and thread0
may block on this mutex before configuring the eventtimer. In this case
the taskqueue thread will sleep forever waiting for its callout to fire.
