[acpica] Only use syscall for sleep state 1-4.

Currently we use the zx_system_powerctl syscall for S state transitions
however only transitions to S3 are supported. As transitions to S5
(shutdown) do not require interrupts to be disabled because caches are
lost regardless, we can allow these transitions to go ahead in ACPICA.
