If CONFIG_ACPI_PROCESSOR=n and CONFIG_ACPI_PROCESSOR_IDLE=n, we may encounter
some warnings about function defined but not used.
All external functions of processor_idle.c are just used in processor_driver.c.
And if CONFIG_ACPI_PROCESSOR is selected and CONFIG_ACPI_PROCESSOR_IDLE also
be selected automatically. So remove these empty function definitions.
