This defines the struct for ACPI APF table. The information included
in this table will be used by guest kernel to retrieve SDEI event
number, PPI number and its triggering properties:
* @sdei_event: number of SDEI event used for page-not-present
* @interrupt: PPI used for page-ready
* @interrupt_flags: PPI's mode and polarity
