ACPI: don't pass handle for fixed hardware notifications

Browse Source 
Fixed hardware devices have no handles, so just pass an explicit
NULL rather than something that looks like it might be meaningful.
acpi_device_notify() doesn't need the handle anyway; the only
reason it takes it as an argument is because the acpi_notify_handler
typedef requires it.
