   Probably a bug, because we could still poll for CPEs w/o ACPI.
Originally the CPE handler was only interrupt driven and the interrupt
is described as a platform interrupt source via ACPI.  So it made sense
then.  CMC have never had an ACPI dependency since the architecture
defines their setup and not the platform.
