ACPI ARM64 architecture implements reduced ACPI profile which doesn't
have GED object. Instead, ARM64 architecture uses onchip peripherals
for similar functionality. If there is a need to signal interrupts,
this is done by ACPI Notify in ASL or if absolutely needed using
ACPI Generic Event Device (GED).
