The penalty determination of ISA IRQ goes through 4 paths.
1. assign PCI_USING during power up via acpi_irq_penalty_init.
2. update the penalty with acpi_penalize_isa_irq function based on the
active parameter.
3. kernel command line penalty update via acpi_irq_penalty_update function.
4. increment the penalty as USING right after the IRQ is assign to PCI.

acpi_penalize_isa_irq and acpi_irq_penalty_update functions get called
before the ACPI subsystem is started.

These API need to bypass the acpi_irq_get_penalty function.
